Merge rust-bitcoin/rust-bitcoin#2644: Add HKDF to bitcoin_hashes 

c9d1ff7037 Update hashes API changes (Nick Johnson)
878ab924d1 Add HMAC Extract-and-Expand Key Derivation Function (Nick Johnson)

Pull request description:

  rustaceanrob and I have been working on a Rust-based BIP324 implementation over at https://github.com/rustaceanrob/bip324. We have been attempting to keep the code pretty clean in hopes of a future "soft landing" in rust-bitcoin. I figured the HKDF implementation is a small, self-contained chunk that might allow us to learn the ropes here first.

  There was a mention in the [discussion thread on BIP324](https://github.com/rust-bitcoin/rust-bitcoin/discussions/1691) that the hashes interface may be changing in the near future. I am not sure the effect that would have on this implementation, but happy to work through any issues.

  Closes #2551
