FreeCAD python script to generate ONERA M6 mesh

The script generates a file with .geo extension to be read by Gmsh mesh generator.

The geometry is based on https://www.grc.nasa.gov/www/wind/valid/m6wing/m6wing.html.
For boundary conditions see https://su2code.github.io/tutorials/Inviscid_ONERAM6.

Tested with

FreeCAD version: 0.18.4
Gmsh version: 4.7.1
