Merge branch 'bug' into m2

Removed an duplicated chi2 printout in the rotor2 CaM frame order test data optimisation script.

Fixed the average position Euler angles for the rotor2 CaM frame order test data optimisation script.

The angles needed to be reversed.

Updated the rotor2 CaM frame order test data optimisation script for the changed notation.

A new set of notations is now being used to try to solve a nasty alpha angle parameterisation bug.

Changed how the rotor axis is calculated in the func_rotor() frame order target function.

A new set of notations is now being used to try to solve a nasty alpha angle parameterisation bug.

Rewrite of the rotor2 CaM test data optimisation script.

This now handles the new rotor frame order model parameterisation. Two functions have been added
for converting between the old and new parameters - alpha_angle() to calculate the new alpha
parameter and shift_pivot() for shifting the pivot to the closest point to the CoM on the rotor
axis.

Fixed the rotor axis direction in the lib.frame_order.rotor_axis module.

The normalisation code has also been simplified.

Fix for the dispersion model_statistics() specific API method.

The spin ID argument should override the model_info argument. The method now correctly implements
this.

Removed an unused comment.
