...graph update
Fixes#1151.
When wallet_esplora_* was used to sync a wallet containing a transaction
confirmed some time ago (more than 10-15 blocks ago), the transaction would
be stuck in an "unconfirmed" state forever.
At the first scan time, `update_local_chain` would just fetch the last 10 to
15 blocks (depending on the server used), and `tx_graph.missing_heights`
wouldn't return the tx's confirmation block as it was called on the
original, non-updated tx_graph.
So, after the first scan, we would have a transaction in memory with an
anchor that doesn't exist in our local_chain, and try_get_chain_position
would return unconfirmed.
When scanning again, missing_heights would find the missing anchor, but
`update_local_chain` wouldn't include it as it's older than
ASSUME_FINAL_DEPTH.
The missing block would be downloaded every time, but never included in
the local_chain, and the transaction would remain unconfirmed forever.
Here we call missing_heights on the updated graph, so that it can
correctly return the anchor height, and `update_local_chain` can
fetch it and include it in the chain.

### Description
Fixes#1063.
This PR introduces a new `TxTemplate` struct to test different transaction conflict scenarios in `TxGraph`.
The following transaction conflict scenarios are tested:
- 2 unconfirmed txs with different last_seens conflict. The most recent tx should be the only tx that appears in the list methods.
- 3 unconfirmed txs with different last_seens conflict. The most recent tx should be the only tx that appears in the list methods.
- An unconfirmed tx U conflicts with a tx anchored in orphaned block O. O has higher last_seen. O should be the only tx that appears in the list methods.
- An unconfirmed tx U conflicts with a tx anchored in orphaned block O. U has higher last_seen. U should be the only tx that appears in the list methods.
- Multiple unconfirmed txs conflict with a confirmed tx. None of the unconfirmed txs should appear in the list methods.
- B and B' conflict. C spends B. B' is anchored in best chain. B and C should not appear in the list methods.
- B and B' conflict. C spends B. B is anchored in best chain. B' should not appear in the list methods.
- B and B' conflict. C spends both B and B'. C is impossible.
- B and B' conflict. C spends both B and B'. C is impossible. B' is confirmed.
- B and B' conflict. C spends both B and B'. C is impossible. D spends C.
These tests revealed that `TxGraph::walk_conflicts` was not checking ancestors of the root tx for conflicts. `TxGraph::walk_conflicts` has been refactored to check for conflicting ancestor transactions by using a new `TxAncestors` iterator in `TxGraph`.
### Changelog notice
- Introduced `tx_template` module
- Introduced `TxGraph::TxAncestors` iterator
- Refactored `TxGraph::walk_conflicts` to use `TxGraph::TxAncestors`
- Added `walk_ancestors` to `TxGraph`

...try_get_chain_pos
In try_get_chain_pos, when we notice that a transaction is not included
in the best chain, we check the transactions in mempool to find
conflicting ones, and decide based on that if our transaction is still
in mempool or has been dropped.
This commit adds a check for transactions conflicting with the
unconfirmed ancestors of our tx.

e6519e3a52 Enhance the documentation for the fee_rate and fee_absolute methods. (Jon Marrs)
Pull request description:
### Description
This pr helps solve this issue: https://github.com/bitcoindevkit/bdk/issues/856
I added documentation to the fee_rate() method to describe the units as either satoshis/vbyte (sats/vbyte) or satoshis/kwu (sats/kwu), depending on the FeeRate type.
I also added documentation to the fee_absolute() method to clarify that the fee is determined by whichever method (fee_rate or fee_absolute) was called last, as the FeePolicy is an enum, and FeeRate/FeeAmount are mutually exclusive.
### Notes to the reviewers
I thought it would be helpful to provide documentation to alleviate confusion over the fee_rate method and the fee_absolute method.

We remove `ElectrumUpdate` and return tuples instead for `ElectrumExt`
methods. We introduce the `IncompleteTxGraph` structure to specifically
hodl the incomplete `TxGraph`.
This change is motivated by @LLFourn's comment: 794bf37e63 (r1305432603)
