Decreased all nr_iter values by 10 and added more dispersion models to the super profiling script.
This is for the dispersion model profiling scripts in test_suite/shared_data/dispersion/profiling/,
all controlled by the disp_profile_all.py super profiling script for generating statistics using all
of the other profiling scripts. The number of iterations needed to be decreased as otherwise it
would now take almost 1 day to generate the statistics table.
