Package tools on PyPI

[oxr463]

Instead of running the tools from within the directory, it would be better to not have compiled .dylib and .so files within the git repository but instead publish them as packages on PyPI. Then one could pip install the tools and even include them in a Dockerfile for running CI/CD.
