Specify rotation order in from_euler_angle(r, p, y) method

It would be quite handy to be able to specify the rotation order in the convenience function, as opposed to having a fixed order. Modern DCCs (Maya, Houdini, etc) which store rotations as Euler angles also store rotation order; if one hopes to author tools which integrate in that world (vfx, animation, etc) it is pretty standard fare.

Thank you for the suggestion! That’s a feature we will consider adding. I’ve created an issue on the nalgebra repository.
