Removed a terrible hack for handling the frame order analysis without constraints.

This is no longer needed as the log-barrier method is now used to constrain the optimisation, so
that the torsion angle can no longer be negative.

Constraints are now implemented in the frame order grid search.

This is useful for the pseudo-elliptic models as the cone theta_x < theta_y constraint halves the
optimisation space.

Expanded the CaM rotor test data frame_order.py optimisation script.

The optimisation is now implemented as in the auto-analysis, with an iterative increase in accuracy
of the quasi-random numerical integration together with an decrease of the function tolerance cutoff
for optimisation. The accuracy of the initial chi-squared calculation is now much higher. And the
accuracy of the initial grid search and the Monte Carlo simulations is now much lower.

The results of the new optimisation are included.

Added one more iteration for the zooming optimisation of the frame order auto-analysis.

This is to improve the speed of optimisation when all RDC and PCS data is being used. The previous
iterations where with [100, 1000, 200000] Sobol' integration points and [1e-2, 1e-3, 1e-4] function
tolerances. This has been increased to [100, 1000, 10000, 100000] and [1e-2, 1e-3, 5e-3, 1e-4].
The final number of points has been decreased as that level of accuracy does not appear to be
necessary. These are also only default values that the user can change for themselves.

Updated the CaM frame order data generation base script to print out more information.

This is for the first axis system so that the same amount of information as the second system is
printed.
