Created the specific_analyses.relax_disp.disp_data.count_frq() function.

This is for determining the number of spectrometer frequencies present, even if not data has been
defined.

Clustering was accidentally turned off in the r1rho_on_res_m61.py system test script.

Improvements for the parameter checks in the system tests for the r1rho_on_res synthetic data.

This includes both the Relax_disp.test_r1rho_on_res_fixed_time_m61 and
Relax_disp.test_r1rho_on_res_exponential_m61 tests.

Speed up of the r1rho_on_res_m61.py system test script.

The optimisation precision is now much lower. And the peak intensity errors now have been scaled by
1000 just as the base data was in the previous commit.

Increased the precision of the Sparky peak lists for the r1rho_on_res dispersion test data.

All peak intensities are now 1000 bigger. As the values are integers in the Sparky files, the
previous values were too truncated for the system tests to properly optimise and find the original
parameters.

Fixes for the lib.dispersion.m61.r2eff_M61() function.

Fixes for the parameter checks in the system tests for the r1rho_on_res synthetic data.

This includes both the Relax_disp.test_r1rho_on_res_fixed_time_m61 and
Relax_disp.test_r1rho_on_res_exponential_m61 tests.

Added a log file for the data generation script for the r1rho_on_res dispersion data.

Removed cdp.model as this makes no sense - a different model can be used per spin cluster.

Now the variable cdp.model_type is used to identify the 'R2eff' model. For all other dispersion
models this variable is set to 'Disp'.

The r1rho_on_res_m61.py dispersion system test script now sets the spectrometer frequency information.
