@sigma67 I added a bit of typing in addition to determining profile type, so it's easier to work with the library on the consumer side. I couldn't propagate it further down the code (e.g., def parse_album(result: JsonDict) -> AlbumInfo:) without refactoring the current typing system because it starts conflicting with ParseFuncType, ParseFuncDictType, ... arg types

If you think that it's gonna introduce unnecessary maintenance overhead, I will roll back the typing addition
