Mypy complains about method decorated with `with_annotated` decorator

[neoniobium]

Problem

Mypy complains about methods decorated with with_annotated when using strict settings.

How to reproduce

class App(Cmd):

    @with_annotated
    def do_something(...) -> None:  # <- Mypy complains here
        ...

Expected behavior

Mypy does not complain.

Actual behavior

Mypy reports:

...: error: Type of decorated function contains type "Any" ("Callable[..., Any]")  [misc]
        def do_something(...)

I think this can be fixed by using ParamSpec instead of the ellipsis notation (Callable[..., Any]). I have not verified it yet.
