Add the Mechanical APDL 'ANF' file type to import_cad

[mikerife]

📝 Description of the feature

In MAPDL the ANF file format, ANF, is the cleanest geometry that it can export. Would it be possible to add importing ANF files? We have many customers with MAPDL scripts that create geometry, and it would be nice to be able to step over to PyPrimeMesh for meshing, then back to MAPDL (via PyMAPDL).

💡 Steps for implementing the feature

No idea. Perhaps it is better for PyGeometry to add an importer for ANF files, then we can export SDOC file and go to PyPrimeMesh from there?

@mikerife is this a standard way of working for many users? Presumably this would be to support geometry creation in MAPDL?
Would there be any issue with migrating to creating geometry in Pyansys-Geometry and then going to PyPrimeMesh?
