Improve Wheel Building Process (#55)

- Pruned directories from external submodules in MANIFEST.in to reduce size of sdist to below one megabyte.
- Use ninja as generator target on supported plattforms in setup.py to improve wheel build times
- Stop building wheels for python3.6 as it's eol since a couple months
