Provide tetrahedra for the scanned objects (deformable simulation)

[jotix16]

It would be handy if the tetrahedra are also provided for all the objects.
That way, the objects could also be used to simulate soft/deformable bodies.

I am doing this for a few objects. If there is interest, I can open a pull request to add tetrahedra for all scanned objects.

I am using https://github.com/wildmeshing/fTetWild as suggested in the doc.
