Is it required to import `from __future__ import annotations` in all the modules?

AFAIU it is going to be deprecated and removed in future versions of Python (https://peps.python.org/pep-0749/) so if we can avoid using it that sounds like a win already.

I don't think it is needed, though I just enabled it as a lint rule. To be sure, maybe remove them after #12 has been done.

As I read it, the deprecation is at least five years away.
