dataclass-wizard incompatible with Python 3.13

[erikpragt-connectid]

• Dataclass Wizard version: 0.23.0
• Python version: 3.13
• Operating System: Mac

Description

In models.py, there's a reference to the private function called _create_fn. This function has been removed in Python 3.13:

https://github.com/python/cpython/blob/2f8301cbfbdd2976d254a4a772b4879069dd4298/Lib/dataclasses.py#L491

As a result, dataclass-wizard no longer works. As a solution, maybe the _create_fn can be copied, or maybe a whole different approach is needed, I'm not sure.

Put up #129 to address this but will need to get @rnag's attention.

Hey guys, sorry for the delay. I'm looking into this now.

@benjjs Your PR looks good and seems it would solve the compatibility issue with 3.13. I added some notes, mostly minor stuff. Let me know when you're able to look into it, but it LGTM otherwise. Thanks!

Closing, as this is fixed by #129.
