In this commit, we add a new interface, the `ScriptDesciptor` to abstract over details of a given output script. The purpose of this interface, and the taproot superset, is to be able to paper over the differences of a p2wsh vs a p2tr output. With this new interface, we can treat them as the same, but then use a type assertion to get at any control block related methods if needed.
