Python314 support

[MysticEntity-dev]

Suggested changes to fix deprecation and changes to format of project.license in python 3.14: C:\Users\XXX\AppData\Local\Temp\pip-build-env-cc_fwjqb\overlay\Lib\site-packages\setuptools\config_apply_pyprojecttoml.py:82: SetuptoolsDeprecationWarning: project.license as a TOML table is deprecated
!!

          ********************************************************************************
          Please use a simple string containing a SPDX expression for `project.license`. You can also use `project.license-files`. (Both options available on setuptools>=77.0.0).

          By 2026-Feb-18, you need to update your project and remove deprecated calls
          or your builds will no longer be supported.

          See https://packaging.python.org/en/latest/guides/writing-pyproject-toml/#license for details.

And also to fix build errors when using the 64 bit MariaDB Connector C, but not sure if this is the correct way.

Ofc this breaks compatibility with all previous python versions. Suggestions welcome as I don't have a lot of time and are quite new to building packages for pip

I don't have Windows box now. Is this current default location of official installer?
