Add support for Python versions 3.12, 3.13, and 3.14

[cleemullins]

Fixes #170

Add newer versions of Python into the build and test matrix. Update docs accordingly. We now call out support for Python 3.12, 3.13, and 3.14. Accord to the Python web site, we now align to the currently supported Python versions (3.10 - 3.14).

Note to reviewers: Once this PR is merged to main, I'll update the GitHub Branch Protection Rules to require the newer builds to pass on all PRs.
