Support python 3 14

fixes #116

[paulclarkaranz]

Hi @tim-mitchell, this PR adds some dependencies to the library which are typically development only dependencies. Namely, bump-my-version, mypy, pre-commit and tox. Since this library is depended on for production use cases, those libraries will now be pulled down by all downstream projects as indirect dependencies.
Please consider moving them to the optional dev dependency group. (If the current dependancy group setup in pyproject.toml isn't working for you, there is apparently a newer standard that the python sdk is using.)

@paulclarkaranz Thanks for pointing this out - I was playing with uv - it must have added them.
