Fix breakage in setuptools-69.0.0 by cleaning up setup.py

Hello,

Setuptools 69.0.0 deprecated a bunch stuff leading to a nasty errors during install.

> File "/tmp/pip-build-env-w815o5v3/overlay/lib/python3.11/site-packages/setuptools/config/_apply_pyprojecttoml.py", line 183, in _license
>          _set_config(dist, "license", val["text"])

__version__.py wasn't used anywhere except setup.py so removing and setting it all pyproject.toml is safe.

During this decided to move as much as I could out of setup.py, zip-safe has been obsolete for modern setuptools installation methods so dropped it.
