feat: Add python3.11 compatibility by using inspect.signature

[franagustin]

• Uses inspect.signature for compatibility with Python3.11 (which does not have getargspec function).
• inspect.signature will be used from Python3.3 onwards, keeping the same behaviour getargspec had.
• getargspec will still be used for Python < 3.3

Hi @alesdotio ,
Thank you for your work on that library. We are using it in our projects :)
We are planning to use Python3.11 and Django4.2 and I would love to help with supporting it.
If you don't have any time on it, I can help you with reviewing MRs and merge them back to master branch. The only needed work would be from your side to release new versions on PyPI so we can get the fresh code which support next Python/Django releases.

Hi @DmytroLitvinov! JFYI, I've been using this branch for Python3.11 and Django4.2 and it's been working so far.
If you try it out and find any issues, please let me know 😁

Hi @franagustin ,
Great!) I also use master branch from that repo and added monkey patch of that PR into my project. It works, but would be better to have it as PyPI released version.

Thanks for PR, by the way :)
