Merge rust-bitcoin#5339: Release tracking PR: bitcoin_hashes v0.18.0

628a2c8 hashes: Bump version to 0.18.0 (Tobin C. Harding)
00cef09 hashes: Remove FromSliceError (Tobin C. Harding)

Pull request description:

  Bump the `hashes` version. Update in all crates that depend on it including adding an explicit version field in `p2p`.
      
  Add a changelog entry and update the lock files.
  
  Before undrafting, remember to run `cargo publish --dry-run -p bitcoin_hashes`
  
  Now removes the `FromSliceError` also. Not sure why we left it in there, was it because we forgot to deprecated it along with `from_slice` (deprecated in `v0.15.0`)?
