from __future__ import annotations breaks dependency injection

Hi. Thank you for the library 🙏 , I am really enjoying it

I found quite a weird edge case: when I import service decorator and there is from __future__ import annotations, then the dependency injection fails with missing {n} required positional arguments error

Hi! Yes, sadly the library won't work at the moment with future annotations as the types are stringified. inspect.get_annotations is also only available from Python 3.10 so this would need a backport.

Looks like typing_extensions will have it in the next release, 4.13.
