More improvements to the model-free over-fitting deselection printouts.

Improved the model-free overfitting deselection printouts prior to optimisation.

Only a single message per spin is now given when the spin is deselected, minimising the amount of
output.

Added a tryptophan NE1 data set to the sphere model-free model test data.

This is in preparation to catch bug #20197 (https://gna.org/bugs/?20197).

The scripts have also been updated for the newer relax designs.

Added the data_check Boolean argument to all of the specific analysis overfit_deselect() methods.

This allows the unit tests to pass.

Fix for bug #20198 (https://gna.org/bugs/?20198) - the relaxation data back-calculation error.

The problem was that the call to the model-free overfit_deselect() method was deselecting any spins
lacking relaxation data! This should not happen, as no spins need to have relaxation data for this
calculation.
