• Rewrite setup.py with pybind11 examples without complex code
• Remove the pybind11 submodule (need to install before build)

Changes in GitHub Actions

• Refactor workflow (build process use GitHub actions)
• Build packages on different platforms and python versions
• Create Release with workflow
• Upload Release to https://pypi.org/

Example of github actions with python and c++ module.

This is not the best solution, but it works!

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

1. Version of cpp-module file
2. Version of wrapper on cpp-module file (module version)

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