Merge rust-bitcoin/rust-bitcoin#2909: bip32: add From<&'a [u32]> for DerivationPath 

a7731b2f33 api: Run just check-api (Marko Bencun)
47cba7a655 bip32: add from_32_slice method to DerivationPath (Marko Bencun)

Pull request description:

  ChildNumber already has a `From<u32>` impl, but converting `&[u32]` to a `DerivationPath` was still difficult.
