Switch to use pyproject.toml instead of setup.py, and skip versioneer

[adybbroe]

This PR started out solving a deprecation warning when installing with pip:

  DEPRECATION: Legacy editable install of pyorbital==1.8.3+29.g19f444b from file:///home/a000680/usr/src/forks/pyorbital (setup.py develop) is deprecated. pip 25.0 will enforce this behaviour change. A possible replacement is to add a pyproject.toml or enable --use-pep517, and use setuptools >= 64. If the resulting installation is not behaving as expected, try using --config-settings editable_mode=compat. Please consult the setuptools documentation for more information. Discussion can be found at https://github.com/pypa/pip/issues/11457

It ended up switching to pyproject.toml, ditching versioneer.py and by using more strict style checkers with ruff many small issues needed attention.

As discussed the one remaining ruff error was a complexity issue with pyorbital/orbital.py:_SGDP4.__init__. I've added an ignore on that method to get ruff to pass. Dealing with the complexity of that method will take a considerable amount of work. My understanding is @pnuu might tackle it if he's foolish enough.

I'm actually already browsing through _SGDP4.__init__. If I have a moment tomorrow I'll have a go at it.
