Simplify WW4 build system

[HendrikTolman-NOAA]

I'd recommend looking at the current WW3 cmake system, as well as some of the other UFS components for inspiration on how to possibly simplify things. Perhaps we can create an issue for simplifying the WW4 build at a minimum if things are not going to be fixed now.

I will add here that I'm very concerned about adding a dependency on python to build C code. Python in particular can be difficult to port to various machines with various flavors of it. I do think having things be accessible to users is important. Perhaps there's a way to be accessible to users while not adding a dependency on python.

The system that was put in place with PR #19 is fully CMake based, removing several of the initial python-based tools. The only additional tool that is left in place is a python-based setup tool. This should solve most of Jessica's issue.

I intend to revisit this once we have a model that is sufficiently mature to do actual wave model runs with.

I also don't quite see why we need a python-based setup tool. So I still have questions/issues.

Starting a branch to remove the python dependence.
