Support for igs and other cad formats #58
Description
Is your feature request related to a problem? Please describe.
Currently igs and other file formats can not be loaded, because the support for gmsh was removed from trimesh in version 4.7.0.
Describe the solution you'd like
A custom loader for these fileformats based on one of python gmsh modules
Describe alternatives you've considered
Convert the model to a different fileformat
Additional context
I recovered this when investigating issue #55
The formats in question should be:
*.brep *.igs *.iges *.bdf *.msh *.inp *.diff *.mesh
