Merge rust-bitcoin/rust-bitcoin#1354: Add `impl IntoIterator for &'_ Witness` 

d2ed0fe022 Add `impl IntoIterator for &'_ Witness` (Martin Habovstiak)

Pull request description:

  It is considered idiomatic for types that have `iter()` method to also implement `IntoIterator` for their references. `Witness` was missing this so it is added here.
