Tiny mesh for the periodic3d_axis regression in su2code/SU2#2963, part 2 of the periodic-boundary series.

navierstokes/periodic3D_axis/wedge.su2 is a 30-degree pipe sector with one cell circumferentially and nodes on the rotation axis. Those nodes kept their initial state in implicit runs; the SU2 fix completes their rotated control volumes and updates their solution.

The mesh generator is included: python3 wedge.py wedge.su2 30 1 1 8 10. No external mesh generator is needed. The SU2 PR includes the regression configuration and before/after pipe comparisons.

30 degree sector of a pipe with one cell in the circumferential direction,
written by wedge.py (python3 wedge.py wedge.su2 30 1 1 8 10).
