Created a script to calculate the R2eff rate errors extremely precisely for Hansen's CPMG data.

This uses 1 million Bootstrap simulations for calculating the errors. The 'r2eff_values.bz2' is
saved after deleting the spin specific r2eff_sim structures so that the file drops from 388 Mb in
size to 7.3 kb.

Updates some scripts for the spectrometer.frequency user function change.

The relaxation dispersion auto-analysis now handles the Bootstrapping simulations.

The bootstrap_sim_num argument can now be passed into the auto-analysis, and the run() method then
executes the relax_disp.r2eff_setup user function.

Created the relax_disp.r2eff_setup user function.

This is required to set the number of Bootstrapping simulations to use in the calc user function.
It replaces the hardcoded variable.

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

This is for determining if a spin has peak intensity for the given spectrometer field strength.

Massively increased the precision of the R2eff error analysis.

The hard-coded simulation number variable is now set to 100000. This appears to be necessary for
reliably reproducing results in the subsequent dispersion models.

Added printouts of the optimised parameters to the Relax_disp.test_hansen_cpmg_data_LM63 system test.

This includes the conversion to the equivalent CPMGFit parameters.

Fixes for the relaxation dispersion auto-analysis for the LM63 model.

The Rex parameter is now the phi_ex parameter.

Fix for the LM63 dispersion model target function - the scaled Phi_ex value is now used for the R2.

The specific_analyses.relax_disp.disp_data.loop_frq() function can now handle missing data.

This allows the loop to yield a single value of None when the spectrometer information has not been
loaded and enables R1rho analyses at a single field strength.
