This is not the best solution, but it works!

We have several versions (changes could be only in the wrapper, but the cpp-module could not be changed)

1. Version of cpp-module file (pkg/src/python_onefile.cpp)
2. Version of python wrapper on cpp-module file (pkg/python/__init__.py)

If cpp-module changes also should be changed module version, but if the wrapper is changed and cpp-module is not changed, then cpp-module version could be not changed.

3. Change release_notes.md with changes.
4. Create a tag that starts with v, e.y. v0.0.1 or version 0.0.1 release or very good (also will trigger as it starts with v).
5. Push
6. Goto GitHub Actions page and choose workflow for your purpose: build and create a record on the release page.
7. If you want to upload to the PyPI server, then add a user/password/token as documented in https://pypi.org/manage/account/token/.
