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.

4ee41dbc402121d14ffa099863bf35329851c1e4 build(esplora): Add async-https-rustls flag to esplora client (thunderbiscuit)
Pull request description:
### Description
The bdk_esplora crate currently doesn't expose the [`async-https-rustls` flag offered by the rust-esplora-client](ef1925e1ee/Cargo.toml (L44)) crate and instead requires users to build using the `default-tls` flag on reqwest, which uses the platform-specific openssl library when compiling. This creates complications for cross-compilation, notably for our Android builds that currently support 3 architectures (`arm64-v8a`, `armeabi-v7a`, and `x86_64`). In order to solve this we can either compile the openssl libraries for each of the platforms we want to support, or use the rustls-tls version of reqwest. The second options is much easier and requires less fiddling with the internals of the Android native development kit and cross-compilation rabbit holes.
Before we merge this I want to make sure I understand the tradeoffs between the `native-tls` and the `rustls-tls` and confirm that there are not potential issues there, but from what I understand they should provide the same functionality/security, and because these are already available/exposed in reqwest and rust-esplora-client, I think this should be a fairly straightforward additional feature we offer.
### Changelog notice
```txt
Added:
- New async-https-rustls feature flag for the bdk_esplora crate, allowing to compile rust-esplora-client using rustls-tls instead of the default native-tls.

The gap limit was checked such as if the last_index was not None but the
last_active_index was, we'd consider having reached it. But the
last_index is never None for this check. This effectively made it so the
gap limit was always 1: if the first address isn't used
last_active_index will be None and we'd return immediately.
Fix this by avoiding error-prone Option comparisons and correctly
checking we've reached the gap limit before breaking out of the loop.

`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.
These methods try to load wallet from persistence and initializes the
wallet instead if non-existant.
An internal helper method `create_signers` is added to reuse code.
Documentation is also improved.
`Wallet::new` now creates a new wallet. `Wallet::load` loads an existing
wallet. The network type is now recoverable from persistence. Error
types have been simplified.

Pull request description:
### Description
Fixes#1142
We would previously sign with whatever x_only_pubkey we had in hand, without first checking if it was the right key or not. This effectively meant that adding multiple taproot PrivateKey signers would produce unbroadcastable transactions.
### Changelog notice
- Fix a bug related to taproot signing with internal keys. We would previously sign with the first private key we had, without checking if it was the correct internal key or not.

the local chain tip to always be a block behind the newest confirmed block.

* `bdk_chain` dependency is added. In the future, we will introduce a
separate `bdk_core` crate to contain shared types.
* replace `Emitter::new` with `from_height` and `from_checkpoint`
* `from_height` emits from the given start height
* `from_checkpoint` uses the provided cp to find agreement point
* introduce logic that ensures emitted blocks can connect with
receiver's `LocalChain`
* in our rpc example, we can now `expect()` chain updates to always
since we are using checkpoints and receiving blocks in order
