util.paseto: Drop custom wrappers around key objects The PASETO spec recommends - no, *requires* - that implementations enforce type safety for keys, and e.g. do not pass them around as arbitrary byte strings. Typed wrapper objects are recommended. I originally followed this advice when starting the lib. However, key wrapping and type safety is now also a feature of util.crypto. All we're doing is duplicating it unnecessarily with this additional wrapper code.
