Previously there was a tx cache that you passed in as part of the sync
request. This seems bad and the example show'd that you should copy all
your transactions from the transaction graph into the sync request every
time you sync'd. If you forgot to do this then you would always download everything.
Instead just do a plain old simple cache inside the electrum client.
This way at least you only download transactions once. You can
pre-populate the cache with a method also and I did this in the examples.
The previous `TxOut` for transactions received from an external
wallet may be optionally added as floating `TxOut`s to `TxGraph`
to allow for fee calculation.
This is more code, but a much more elegant solution than having
`ElectrumExt` methods return `SyncResult`/`FullScanResult` and having an
`ElectrumResultExt` extention trait.
`ElectrumResultExt` trait is also introduced that adds methods which can
convert the `Anchor` type for the update `TxGraph`.
We also make use of the new `TxCache` fields in
`SyncRequest`/`FullScanRequest`. This way, we can avoid re-fetching full
transactions from Electrum if not needed.
Examples and tests are updated to use the new `ElectrumExt` API.
This PR removes `RelevantTxids` from the electrum crate and tracks
transactions in a `TxGraph`. This removes the need to separately
construct a `TxGraph` after a `full_scan` or `sync`.

<!-- You can erase any parts of this template not applicable to your Pull Request. -->
### Description
It's being used on `Balance`, and throughout the code, an `u64` represents the amount, which relies on the user to infer its sats, not millisats, or any other representation.
It updates the usage of `u64` on `Balance`, and other APIs:
- `TxParams::add_recipient`
- `KeyChainTxOutIndex::sent_and_received`, `KeyChainTxOutIndex::net_value`
- `SpkTxOutIndex::sent_and_received`, `SpkTxOutIndex::net_value`
<!-- Describe the purpose of this PR, what's being adding and/or fixed -->
### Notes to the reviewers
<!-- In this section you can include notes directed to the reviewers, like explaining why some parts
of the PR were done in a specific way -->
It updates some of the APIs to expect the `bitcoin::Amount`, but it does not update internal usage of u64, such as `TxParams` still expects and uses `u64`, please see the PR comments for related discussion.
### Changelog notice
<!-- Notice the release manager should include in the release tag message changelog -->
<!-- See https://keepachangelog.com/en/1.0.0/ for examples -->
- Changed the `keychain::Balance` struct fields to use `Amount` instead of `u64`.

- update all fields `immature`, ` trusted_pending`, `unstrusted_pending`
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".
and `into_confirmation_time_tx_graph`, since now it makes
sense to use `TxGraph::update_last_seen_unconfirmed`.
Also, use `update_last_seen_unconfirmed` in examples for
electrum/esplora. We show how to update the last seen
time for transactions by calling `update_last_seen_unconfirmed`
on the graph update returned from a blockchain source, passing
in the current time, before applying it to another `TxGraph`.
