Crate bdk_electrum

This crate is used for updating structures of the bdk_chain crate with data from electrum.

The star of the show is the ElectrumExt::scan method, which scans for relevant blockchain data (via electrum) and outputs updates for bdk_chain structures as a tuple of form:

(bdk_chain::local_chain::Update, RelevantTxids, keychain_update)

An RelevantTxids only includes txids and no full transactions. The caller is responsible for obtaining full transactions before applying. This can be done with these steps:

1. Determine which full transactions are missing. The method missing_full_txs of RelevantTxids can be used.

2. Obtaining the full transactions. To do this via electrum, the method batch_transaction_get can be used.

Refer to bdk_electrum_example for a complete example.
