MinkowskiRound modules unifying + aligned geodesic polyhedron

Separate modules for MinkowskiRound for inner/outer/both edges rounding shared most of code. Thus seemed worth unifying into one with parameters to disable unneeded minkowski() steps.

And changed sphere to axis aligned geodesic polyhedron (made from multiple same sized triangles unlike openscad's sphere of varying size segments) which seems helping a bit to simplify geometry & improve render performance.
Sorry in advance for unreadable coding style due prefering compactness.

If will seem useful, feel free to reuse/adapt (with proper code formatting fix), none attribution to me needed, except to geodesic sphere author, whose code i used too.
