Python 3.9 typing incompatibility.

[RedTTG]

extism isn't compatible with python 3.9's typing

    from extism import Plugin
  File ".venv/lib/python3.9/site-packages/extism/__init__.py", line 6, in <module>
    from .extism import (
  File ".venv/lib/python3.9/site-packages/extism/extism.py", line 238, in <module>
    class Function:
  File ".venv/lib/python3.9/site-packages/extism/extism.py", line 243, in Function
    def __init__(self, namespace: str | None, name: str, args, returns, f, *user_data):
TypeError: unsupported operand type(s) for |: 'type' and 'NoneType'

Are you able to use 3.11+ or is there a reason why you need 3.9 compatibility? 3.11+ is listed as a requirement:

python-sdk/pyproject.toml

Line 7 in 2e83a8c

requires-python = ">=3.11"

Yes I explicitly need 3.9 and on pypi it says 3.9 but I guess only version 1.0.0

Got it, sorry, just saw https://discord.com/channels/1011124058408112148/1050088157737140265/1325471298897444969 and later comments after posting.

I hope you can fix this, if it's just typing I'm sure you can run through the code and fix any type hints. Want me to do it and send a pull request?
