Fixed python3.14 type annotation issue

[MattBurn]

Apologies for the delayed response and sorry I didn't notice the file reformatting. I have updated my branch to be in sync with master and added the single line change.

Fixes issue #198

Thanks for the fix.

Optional: Could you update the README and the installation.rst to change the minimum python version to 3.10 (instead of 3.8 – probably should have been done in PR #200)?

Great! I really needed this fix as well. Although I'm not sure if it's maybe better to use inspect.get_annotations() or even better typing.get_type_hints(obj) instead which might be more future proof. Python 3.14 apparently lazily evaluates the annotations so it's better to not access the __annotations__ attribute.

I'll merge this for now.

Follow-up TODOs:

• update README with minimum python version 3.10 (follow-up to chore: Drop Python <=3.9, upgrade workflow extensions #200)
• Use typing.get_type_hints(obj) instead of type(obj).__annotations__
