New issue 609: Remove delaunay triangulation

Matthew Turk:

As noted in #608, we still ship C++ in the form of the Delaunay Triangulation code.  This code is now included and maintained in Matplotlib.  We should remove ours and rely on the upstream version.

Additionally, in service of removing C++ code we can remove the `_ramses_headers` and the entire RAMSES frontend from 2.X.
