Merge rust-bitcoin/rust-bitcoin#2765: Flesh out hex unit parsing API

cf3e1eb198 api: Run just check-api (Tobin C. Harding)
98bf213c52 bitcoin: Remove error module (Tobin C. Harding)
a5b93cb159 Flesh out hex unit parsing API (Tobin C. Harding)

Pull request description:

  Add to `units::parse` the complete suit of hex unit parsing functions:

  - remove prefix
  - assert without prefix
  - parse with or without prefix
  - parse with prefix
  - parse without prefix
  - parse prefix unchecked

  Refactor `bitcoin` to use the exact function we need, removing code duplication.

  This is a breaking change to `units`, it does however keep the current re-exports from the public, now empty, `bitcoin::error` module.
