The .cpp file released with this package to PyPI was built using an older version of Cython that is incompatible with Python 3.11. This package is not actively maintained, so it's unclear when the fix for this will be merged and released.

In the meantime, we can include a newer version of Cython locally, which will be used instead to regenerate the .cpp file.

Maybe we should keep that even after the change is merged to make sure the files are always up to date unless it creates more maintenance work than it fixes.
