PrusaSlicer 2.2.0 and dependencies

there's apparently lots of new dependencies, or maybe newer versions
are needed. I've added them to the PrusaSlicer ebuild, and added the
ebuilds for them.

Seems to work

+  Qhull computes the convex hull, Delaunay triangulation, Voronoi
+  diagram, halfspace intersection about a point, furthest-site
+  Delaunay triangulation, and furthest-site Voronoi diagram. The
+  source code runs in 2-d, 3-d, 4-d, and higher dimensions. Qhull
+  implements the Quickhull algorithm for computing the convex hull. It
+  handles roundoff errors from floating point arithmetic. It computes
+  volumes, surface areas, and approximations to the convex hull. 
+  Qhull does not support constrained Delaunay triangulations,
+  triangulation of non-convex surfaces, mesh generation of non-convex
+  objects, or medium-sized inputs in 9-D and higher.
