Release 1.0.0-alpha.4

Summary

This release improves the KeychainTxOutIndex API and contains a few bug fixes and performance improvements.

Changelog

Fixed

• Avoid using BTreeMap::append due to performance issues (refer to rust-lang/rust#34666 (comment)). #1274

Changed

• The old hardwaresigner module has been moved out of bdk and inside a new bdk_hwi crate. #1161
• Wallet's peek-address logic is optimized by making use of <SpkIterator as Iterator>::nth. #1269
• KeychainTxOutIndex API is refactored to better differentiate between methods that return unbounded vs stored spks. #1269
• KeychainTxOutIndex no longer directly exposes SpkTxOutIndex methods via DeRef. This was problematic because SpkTxOutIndex also contains lookahead spks which we want to hide. #1269

Added

• LocalChain::disconnect_from method to evict a chain of blocks starting from a given BlockId. #1276
• SpkIterator::descriptor method which gets a reference to the internal descriptor. #1269
