Introducing an in-tree build backend which programmatically detects whether NetCDF4 supports parallel I/O, and if so adds MPI4Py to the list of build dependencies. The custom backend is a very thin wrapper around the original Setuptools backend.

You might want to report which nc-config it's trying to run. Currently the Windows builds are failing with FileNotFoundError: [WinError 2] The system cannot find the file specified which doesn't include the path, annoyingly!

Many apologies, this PR has fallen out of my radar for too long... So far, CI on Windows fails since nc-config cannot be found. May be the PATH needs to be modified before trying to pip-install the package? Unfortunately, I don't have a Windows machine at disposal to do proper debug offline.
