The previous commit b9c5b9d08b040faf6c6b2d9b3745918031555b72 added
IndexSpk. This goes further and adds `Indexed` and `KeychainIndexed`
type alises (IndexSpk is Indexed<ScriptBuf>) and attempts to standardize
the structure of return types more generally.
The underlying SpkTxOutIndex should not use DescriptorIds to index
because this loses the ordering relationship of the spks so queries on
subranges of keychains work.
Along with that we enforce that there is a strict 1-to-1 relationship
between descriptors and keychains. Violating this leads to an error in
insert_descriptor now.
In general I try to make the translation layer between the SpkTxOutIndex
and the KeychainTxOutIndex thinner. Ergonomics of this will be improved
in next commit.
The test from the previous commit passes.

deps(bitcoind_rpc): bump `bitcoin` to `0.32.0`, `bitcoincore-rpc` to

fix(bitcoind_rpc): use `compute_txid()` instead of `txid`
fix(nursery/tmp_plan): use proper `sighash` errors, and fix the expected
`Signature` fields
fix(sqlite): use `compute_txid()` instead of `txid`
deps(hwi): bump `hwi` to `0.9.0`
deps(wallet): bump `bitcoin` to `0.32.0`, miniscript to `12.0.0`
fix(wallet): use `compute_txid()` and `minimal_non_dust()`
- update to use `compute_txid()` instead of deprecated `txid()`
- update to use `minimal_non_dust()` instead of `dust_value()`
- remove unused `bitcoin::hex::FromHex`.
fix(wallet): uses `.into` conversion on `Network` for `NetworkKind`
- uses `.into()` when appropriate, otherwise use the explicit
`NetworkKind`, and it's `.is_mainnet()` method.
fix(wallet): add P2wpkh, Taproot, InputsIndex errors to `SignerError`
fix(wallet): fields on taproot, and ecdsa `Signature` structure
fix(wallet/wallet): convert `Weight` to `usize` for now
- converts the `bitcoin-units::Weight` type to `usize` with help of
`to_wu()` method.
- it should be updated/refactored in the future to handle the `Weight`
type throughout the code instead of current `usize`, only converting
it for now.
- allows the usage of deprecated `is_provably_unspendable()`, needs
further discussion if suggested `is_op_return` is suitable.
- update the expect field to `signature`, as it was renamed from `sig`.

internally
fix(wallet/wallet): remove `0x` prefix from expected `TxId` display
fix(examples): use `compute_txid()` instead of `txid`
fix(ci): remove usage of `bitcoin/no-std` feature
- remove comment: `# The `no-std` feature it's implied when the `std` feature is disabled.`
This fixes the bug with changesets not being monotone. Previously, the
result of applying changesets individually v.s. applying the aggregate
of changesets may result in different `KeychainTxOutIndex` states.
The nature of the changeset allows different keychain types to share the
same descriptor. However, the previous design did not take this into
account. To do this properly, we should keep track of all keychains
currently associated with a given descriptor. However, the API only
allows returning one keychain per spk/txout/outpoint (which is a good
API).
Therefore, we rank keychain variants by `Ord`. Earlier keychain variants
have a higher rank, and the first keychain will be returned.
We only need to loop though entries of `other`. The logic before was
wasteful because we were also looping though all entries of `self` even
if we do not need to modify the `self` entry.
- The KeychainTxOutIndex's internal SpkIterator now uses DescriptorId
instead of K. The DescriptorId -> K translation is made at the
KeychainTxOutIndex level.
- The keychain::Changeset is now a struct, which includes a map for last
revealed indexes, and one for newly added keychains and their
descriptor.
API changes in bdk:
- Wallet::keychains returns a `impl Iterator` instead of `BTreeMap`
- Wallet::load doesn't take descriptors anymore, since they're stored in
the db
- Wallet::new_or_load checks if the loaded descriptor from db is the
same as the provided one
API changes in bdk_chain:
- `ChangeSet` is now a struct, which includes a map for last revealed
indexes, and one for keychains and descriptors.
- `KeychainTxOutIndex::inner` returns a `SpkIterator<(DescriptorId, u32)>`
- `KeychainTxOutIndex::outpoints` returns a `impl Iterator` instead of `&BTreeSet`
- `KeychainTxOutIndex::keychains` returns a `impl Iterator` instead of
`&BTreeMap`
- `KeychainTxOutIndex::txouts` doesn't return a ExactSizeIterator
anymore
- `KeychainTxOutIndex::unbounded_spk_iter` returns an `Option`
- `KeychainTxOutIndex::next_index` returns an `Option`
- `KeychainTxOutIndex::last_revealed_indices` returns a `BTreeMap`
instead of `&BTreeMap`
- `KeychainTxOutIndex::reveal_to_target` returns an `Option`
- `KeychainTxOutIndex::reveal_next_spk` returns an `Option`
- `KeychainTxOutIndex::next_unused_spk` returns an `Option`
- `KeychainTxOutIndex::add_keychain` has been renamed to
`KeychainTxOutIndex::insert_descriptor`, and now it returns a
ChangeSet
We plan to record `Descriptor` additions into persistence. Hence, we
need to add `Descriptor`s to the changeset. This depends on
`miniscript`. Moving this into `txout_index.rs` makes sense as this is
consistent with all the other files. The only reason why this wasn't
this way before, is because the changeset didn't need miniscript.

`txouts` and `txouts_in_tx` are exposed from `SpkTxOutIndex`, but
modified to remove nested unions.
Add `keychain_outpoints_in_range` that iterates over outpoints of a
given keychain derivation range.
Previously `SpkTxOutIndex` methods can be called from
`KeychainTxOutIndex` due to the `DeRef` implementation. However, the
internal `SpkTxOut` will also contain lookahead spks resulting in an
error-prone API.
`SpkTxOutIndex` methods are now not directly callable from
`KeychainTxOutIndex`. Methods of `KeychainTxOutIndex` are renamed for
clarity. I.e. methods that return an unbounded spk iter are prefixed
with `unbounded`.
Simplify the `reveal_to_target` algorithm by exiting prematurely if
the `target_index` is already revealed.
Since the `reveal_to_index` variable was different from
`Some(target_index)` only if the target was already revealed, we can
getrid of the variable altogether.
The wallet is currently created without setting any lookahead value for
the keychain. This implicitly makes it a lookahead of 0. As this is a
high-level interface we should avoid footguns and aim for a reasonable
default.
Instead of simply patching it for wallet, we alter `KeychainTxOutIndex`
to have a default lookahead value. Additionally, instead of a
per-keychain lookahead, the constructor asks for a `lookahead` value.
This avoids the footguns of having methods which allows the caller the
decrease the `lookahead` (and therefore panicing). This also simplifies
the API.

Other changes:
* The `async-https` feature of `bdk_esplora` is no longer default.
* Rename `ObservedAs` to `ChainPosition`.
* Set temporary MSRV to 1.60.0 to compile all workspace members will all
features.
Instead of relying on a `OwnedIndexer` trait to filter for relevant
txouts, we move the listing and balance methods from `IndexedTxGraph` to
`TxGraph` and add an additional input (list of relevant outpoints) to
these methods.
This provides a simpler implementation and a more flexible API.
SpkIterator was created with its own nth() and next() implementations
and its own new() and new_with_range() constructors.

Previously, I have misunderstood the definition of anchor. If a tx is
anchored in a block, it does not necessarily mean it is confirmed in
that block. The tx can be confirmed in an ancestor block of the anchor
block.
With this new definition, we need a new trait `ConfirmationHeight` that
has one method `confirmation_height`. This trait can be used to extend
`Anchor` for those implementations that can give us the exact
conirmation height of a tx (which is useful in most cases).
Another change is to add another variant to the `ObservedAs` enum;
`ObservedAs::ConfirmedImplicit(A)`. If a tx does not have an anchor, but
another tx that spends it has an anchor that in in the best chain, we
can assume that tx is also in the best chain. The logic of
`TxGraph::try_get_chain_position` is also changed to reflect this.
Some methods from `IndexedTxGraph` have been moved to `TxGraph` as they
do not require the `Indexer`. Some `TxGraph` methods have been renamed
for clarity and consistency.
Also more docs are added.
