Subject: [PATCH] Enforce the extension module in setup.py

Without this change, [cibuildwheel](https://github.com/pypa/cibuildwheel) cannot build a correct wheel from the generated project. The problem is that the native lib is added by `MANIFEST.in` and `python3 -m pip wheel` ignores it and thinks that the package is pure Python. Thefore it builds a pure wheel and the packaging pipeline crashes.
