Update python versions in CI. Replace point-in-polygon algorithm.

[fakufaku]

This PR updates the python versions in the build system.

• Python 3.7 is removed due to end-of-life
• Adds Python 3.11 and 3.12

The update revealed some bugs in the point-in-polygon algorithm used in libroom.
The old crossing based algorithm was replaced with the winding number algorithm.

• Are there docstrings ? Do they follow the numpydoc style ?
• Have you run the tests by doing nosetests or py.test at the root of the repo ?
• Have you checked that the doc builds properly and that any new file has been added to the repo ? How to do that is covered in the documentation.
• Is there a unit test for the proposed code modification ? If the PR addresses an issue, the test should make sure the issue is fixed.
• Last but not least, did you document the proposed change in the CHANGELOG file ? It should go under "Unreleased".
