Support for Pydantic2

[Andrew-S-Rosen]

I saw that Pydantic is pinned to < 2. It'd be good to eventually add support for Pydantic 2. I don't think this should be particularly hard, seeing as the only instance of calling pydantic is in the models module.

Note: I'm not asking you to do this :) just making a note. I might tackle it when a get a spare moment! Most of my software stack is now set to pydantic >= 2.

Thanks for pointing this out! I haven't learned Pydantic v2 yet and haven't encountered an environment problem due to pinning, but know it is coming 😬
