Added 3 unit tests for reduce_alignment_tensor().

daeg_to_rotational_superoperator() now operates on the Kronecker product form.

Modified the pseudo-ellipse frame order matrix point unit tests.

Reactivated the test_compile_2nd_matrix_pseudo_ellipse_order() frame order unit test.

The tmax_pseudo_ellipse() fn now handles the zero points correctly.

Large simplifications to the equations of the pseudo-ellipse frame order model.

This significantly increases the numerical stability and allows parameters to be close to zero.

Fix for the test_compile_2nd_matrix_pseudo_ellipse_restriction_test3() frame order unit test.

Simplified populate_2nd_eigenframe_iso_cone() even further.

This should bring some numerical stability.

Added 9 unit tests for the parametric restriction collapse of all frame order model compile_2nd_matrix*() fns.

Bug fix for the iso cone frame order model fn populate_2nd_eigenframe_iso_cone().

A few signs were wrong in the {0,4} and {4,0} element.
