- 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.

Pull request description:
Fixes#1199
### Description
After a second look at the `update_local_chain` implementations, it was clear that they were over complicated. This PR simplifies the `EsploraExt::update_local_chain` method(s) of the `bdk_esplora` crate and adds a whole bunch of tests.
### Notes to the reviewers
The description of #1199 is very brief, however @danielabrozzoni mentioned about potentially-problematic logic with `ASSUME_FINAL_DEPTH`. The logic was indeed convoluted and it did not need to be that way. This PR removes the need for `ASSUME_FINAL_DEPTH`.
### Changelog notice
Fixed
- Simplified `EsploraExt::update_local_chain` logic.

### Description
We now filter out duplicate coins before calling `CoinSelectionAlgorithm::coin_select`. If a UTXO exists in both `required_utxos` and `optional_utxos`, only the copy in `required_utxos` will be kept.
Test helper methods are also updated to not create duplicate UTXOs.

Pull request description:
### Description
`EntryIter` performance is improved by reducing syscalls. The underlying file reader is wrapped with `BufReader` (to reduce calls to `read` and `seek`).
Two new tests are introduced. One ensures correct behavior when the last changeset write is too short. The other ensures the next write position is correct after a short read.

Because we use wrap the file with `BufReader` with the `EntryIter`, we
need to sync the `BufReader`'s position with the file's offset when we
drop the `EntryIter`. Therefore we have a custom drop impl for
`EntryIter`.
ed91a4bdb4 Consolidate `calc_checksum_bytes_internal` routine (Sebastian Falbesoner)
179cfeff51 Remove deprecated `get_checksum{,_bytes}` routines (Sebastian Falbesoner)
Pull request description:
### Description
This PR removes the routines `get_checksum` and `get_checksum_bytes` (in the bdk crate, descriptor/checksum.rs), which have been deprecated in 0.24.0. Consequently, the routine `calc_checksum_bytes_internal` is consolidated into `calc_checksum_bytes`, as the boolean parameter `exclude_hash` is not needed anymore. See also the two TODOs in the touched file.
### Notes to the reviewers
In the second commit, the signature of the function `calc_checksum_bytes` slightly changes, as the `desc` parameter now is declared as `mut`, in order to change the local variable within the function. My rust experience is rather limited, so I'm not sure if this is a problem for users. IIUC, this is comparable to changing a pass-by-value parameter in C++ from `const std::string desc` to `std::string desc`, which is relevant only for the function implementation, but doesn't change the interface.

Pull request description:
### Description
Introduce block-by-block API for `bdk::Wallet`. A `wallet_rpc` example is added to demonstrate syncing `bdk::Wallet` with the `bdk_bitcoind_rpc` chain-source crate.
The API of `bdk_bitcoind_rpc::Emitter` is changed so the receiver knows how to connect to the block emitted.
### Notes to the reviewers
### Changelog notice
Added
* `Wallet` methods to apply full blocks (`apply_block` and `apply_block_connected_to`) and a method to apply a batch of unconfirmed transactions (`apply_unconfirmed_txs`).
* `CheckPoint::from_block_ids` convenience method.
* `LocalChain` methods to apply a block header (`apply_header` and `apply_header_connected_to`).
* Test to show that `LocalChain` can apply updates that are shorter than original. This will happen during reorgs if we sync wallet with `bdk_bitcoind_rpc::Emitter`.
Fixed
* `InsertTxError` now implements `std::error::Error`.

Pull request description:
Closes#1268
### Description
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`.
In addition to this, I also optimized the peek-address logic of `bdk::Wallet` using the optimized `<SpkIterator as Iterator>::nth` implementation.
### Notes to the reviewers
This is mostly refactoring, but can also be considered a bug-fix (as the API before was very problematic).
### Changelog notice
Changed
* Wallet's peek-address logic is optimized by making use of `<SpkIterator as Iterator>::nth`.
* `KeychainTxOutIndex` API is refactored to better differentiate between methods that return unbounded vs stored spks.
* `KeychainTxOutIndex` no longer directly exposes `SpkTxOutIndex` methods via `DeRef`. This was problematic because `SpkTxOutIndex` also contains lookahead spks which we want to hide.
Added
* `SpkIterator::descriptor` method which gets a reference to the internal descriptor.

`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.
