Rework sqlite: Instead of only supported one schema (defined in
`bdk_sqlite`), we have a schema per changeset type for more flexiblity.
* rm `bdk_sqlite` crate (as we don't need `bdk_sqlite::Store` anymore).
* add `sqlite` feature on `bdk_chain` which adds methods on each
changeset type for initializing tables, loading the changeset and
writing.
Rework changesets: Some callers may want to use `KeychainTxOutIndex`
where `K` may change per descriptor on every run. So we only want to
persist the last revealed indices by `DescriptorId` (which uniquely-ish
identifies the descriptor).
* rm `keychain_added` field from `keychain_txout`'s changeset.
* Add `keychain_added` to `CombinedChangeSet` (which is renamed to
`WalletChangeSet`).
Rework persistence: add back some safety and convenience when persisting
our types. Working with changeset directly (as we were doing before) can
be cumbersome.
* Intoduce `struct Persisted<T>` which wraps a type `T` which stores
staged changes to it. This adds safety when creating and or loading
`T` from db.
* `struct Persisted<T>` methods, `create`, `load` and `persist`, are
avaliable if `trait PersistWith<Db>` is implemented for `T`. `Db`
represents the database connection and `PersistWith` should be
implemented per database-type.
* For async, we have `trait PersistedAsyncWith<Db>`.
* `Wallet` has impls of `PersistedWith<rusqlite::Connection>`,
`PersistedWith<rusqlite::Transaction>` and
`PersistedWith<bdk_file_store::Store>` by default.
Rework wallet-construction: Before, we had multiple methods for loading
and creating with different input-counts so it would be unwieldly to add
more parameters in the future. This also makes it difficult to impl
`PersistWith` (which has a single method for `load` that takes in
`PersistWith::LoadParams` and a single method for `create` that takes in
`PersistWith::CreateParams`).
* Introduce a builder pattern when constructing a `Wallet`. For loading
from persistence or `ChangeSet`, we have `LoadParams`. For creating a
new wallet, we have `CreateParams`.
Remove `PersistBackend`, `PersistBackendAsync`, `StageExt` and
`StageExtAsync`. Remove `async` feature flag and dependency. Update
examples and wallet.
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(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.

- 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::insert_descriptor`, and now it returns a
ChangeSet

and `confirmed` to use the `bitcoin::Amount` instead of `u64`
- update all `impl Balance` methods to use `bitcoin::Amount`
- update all tests that relies on `keychain::Balance`
Upgrade:
- bitcoin to v0.31.0
- miniscript to v11.0.0
Note: The bitcoin upgrade includes improvements to the
`Transaction::weight()` function, it appears those guys did good, we
no longer need to add the 2 additional weight units "just in case".
- Add typedefs to model the result of functions `planned_utxos`
and `init`
- Add new struct `CreateTxChange` to hold any change info
resulting from `create_tx`
These changes help resolve clippy::type_complexity
These lints either resolved themselves, or the code has changed such that
they no longer apply, hence they can be removed with no further changes.

In the example_cli we were not always committing (seemingly by mistake).
This then caused all the examples to have to compensate by manually
committing.
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`.
`PersistBackend::is_empty` is removed. Instead, `load_from_persistence`
returns an option of the changeset. `None` means persistence is empty.
This is a better API than a separate method. We can now differentiate
between a persisted single changeset and nothing persisted.
`Store::aggregate_changeset` is refactored to return a `Result` instead
of a tuple. A new error type (`AggregateChangesetsError`) is introduced
to include the partially-aggregated changeset in the error. This is a
more idiomatic API.
Instead of inserting anchors and seen_at timestamp in the same method,
we have three separate methods. This makes the API easier to understand
and makes `IndexedTxGraph` more consistent with the `TxGraph` 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.
This corresponds to `keychain::KeychainChangeSet` but for the redesigned
structures with `LocalChain`.
This structure is now used in `Wallet` as well as the examples.
