in case no normal and up-vectors can be read from the star file, we use the normal vector from the mesh and initialize a random up-vector.

These lines are necessary to alter the orientations of loaded positions

When loading points, this function was called on an empty features table, leading to an error and thus orientation vectors were not loaded properly in Surforama.

I encountered some issues when loading points from star files into Surforama (even those generated in Surforama).
This PR should fix these issues and also add the functionality to load star files that do not contain orientation information.
In this case, the normal vector is computed from the nearest triangle and a perpendicular up-vector is assigned.
Previous issues:
Please find more details in the commented code.
Let me know what you think :)
