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`.
- Changed the `add_recipient` method on `TxBuilder` implementation to expect `bitcoin::Amount`.
- Changed the `sent_and_received`, and `net_value` methods on `KeyChainTxOutIndex` to expect `bitcoin::Amount`.
- Changed the `sent_and_received`, and `net_value` methods on `SpkTxOutIndex` to expect `bitcoin::Amount`.

- 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`.
