Release v3.0.0

[forrestfwilliams]

This is the first of several major refactoring efforts for this repository. In this release we are removing all functionality not being used internally at ASF and getting the repository up to our current formatting and CI/CD standards. Expect another major release that will further migrate some functionality and perform some breaking refactoring changes.

I opened #294 to clean up the Python version stuff, which should resolve all my requested changes.

Confirmed this version of hyp3lib works in hyp3-isce2, so I think we are g2g to move forward.
