@Antelox 9cfd5cfac3 - Improved the GitHub python binding workflow: (#2072)
- Added fullMode input in workflow_dispatch
    - Take decision whether to build either in debug or release mode and if to build for all python versions according to the commit message patterns
    - Set proper artifact names
    - Removed not needed steps
    - Compacted some steps in order to leverage more the matrix feature
    - Bumped cibuildwheel action to 2.22.0
    - Run actual regress tests in place of sample scripts
- Specify optional test install in pyproject.toml with proper requirements
- Derive package version from git tags
- Add GENERATORS env var support in setup.py to specify cmake generator and minor refactoring
- Minor cleanup/refactoring for the regress test suite
- Marked some regress tests with skipIf to skip them in case of old python versions
- Marked some failing regress tests to be checked with skipIf
