Added relax_disp.set_grid_r20_from_min_r2eff functionality to relax disp auto_analyses.

Feature request: #3151, (https://gna.org/support/index.php?3151) - User function to set the R20 parameters in the default grid search using the minimum R2eff value.

Modified systemtest to use user function instead.

Feature request: #3151, (https://gna.org/support/index.php?3151) - User function to set the R20 parameters in the default grid search using the minimum R2eff value.

Added user function: relax_disp.set_grid_r20_from_min_r2eff.

Feature request: #3151, (https://gna.org/support/index.php?3151) - User function to set the R20 parameters in the default grid search using the minimum R2eff value.

Extended api value.set to use index in value setting.

Feature request: #3151, (https://gna.org/support/index.php?3151) - User function to set the R20 parameters in the default grid search using the minimum R2eff value.

The index used is expected to match the spectrometer frequency.

Added systemtest for setting R20 from minimum R2eff before grid search.

Feature request: #3151, (https://gna.org/support/index.php?3151) - User function to set the R20 parameters in the default grid search using the minimum R2eff value.

Systemtest: -s Relax_disp.test_sod1wt_t25_set_grid_r20_from_min_r2eff.

Added function to find minimum R2eff value to set as R20 value before grid search.

Feature request: #3151, (https://gna.org/support/index.php?3151) - User function to set the R20 parameters in the default grid search using the minimum R2eff value.

Changed the bounds for the R20 parameters in the default grid search.

The range of 1 to 40 rad.s^-1 was previous used. This has been narrowed to 5 to 20.

Large speed up of the relaxation dispersion system tests by about 20%.

This was achieved by turning the grid search off in the following system tests:
Relax_disp.test_hansen_cpmg_data_auto_analysis
Relax_disp.test_hansen_cpmg_data_auto_analysis_numeric
Relax_disp.test_hansen_cpmg_data_auto_analysis_r2eff
Relax_disp.test_hansen_cpmg_data_missing_auto_analysis
Relax_disp.test_m61_exp_data_to_m61

Some of the optimisation values are slightly different, or completely different for the one example
of the CR72 model fitted to no exchange, and these have been updated in the tests.

Expanded the dispersion specific API set_param_values() method for the 'r2eff' and 'i0' parameters.

This now sets these parameter values correctly if the value sent into the method is not composed of
dictionaries.

The R2eff dispersion parameter now also defaults to 10 rad.s^-1.
