Allow annotations to be optional when @typed

[chtenb]

class Foo:
    @typed
    def validate(self, string: str): # TypeError: Annotation doesn't match function signature
        ...

It'd be great if this would not give an error, but just limit the checking to the annotated variables.

I think this project is dead - the last commit was two years ago. Any confirmation, @dobarkod?
