Enhancement: Add XYZ axis labels to the origin axis marker

[SummerStorm]

I would like to propose an enhancement. Most 3D software have the three axis labelled on the axis marker. As of 1.0.0, ocp-cad-viewer does not have this feature yet. It would be nice to have the axis labelled.

This relevant SO question may offer some help, I think copying the camera quaternion is probably the right thing to do:

Thanks for adding this finding to the issue @jdegenstein

@SummerStorm can you close this issue as this feature has been added to OCP (upstream in three-cad-viewer)?
