Infrastructure Updates

[jpn--]

This PR updates some of the packaging infrastructure.

• setup.cfg and setup.py are completely removed in favor of moving all setup into the pyproject.toml file, consistent with latest Python packaging practices.
• The minimum Python version is pushed to 3.10 (primarily to allow type annotations in X | Y format, for ease of use with Pydantic).
• The sparse package is added as a required dependency. This package is required for 2-zone models, and adds very little overhead to the install even for 1-zone models; it is easier to install it all the time rather than rely on users to know if it would be needed or not.

I tested the installation on my windows laptop, it worked fine and ran the example mtc model. I had one question in my other comment.

I'm leaving this as is -- every time we have a PR against main, if it passes the foundational tests then we build and push the documentation to the "develop" subdirectory where our in-development docs live. There are other actions that push docs for specific releases etc.
