Added systemtest Relax_disp.test_estimate_r2eff_error().

This is to get insight in the error difference between 2000 monto carlo simulations and then scipy.optimize.leastsq.

task #7822(https://gna.org/task/index.php?7822): Implement user function to estimate R2eff and associated errors for exponential curve fitting.

Modified systemtest Relax_disp.test_estimate_r2eff.

This is to compare against errors simulated with 2000 MC.

The paramaters are comparable, but not equal.
Mostly, it seems that the errors from scipy.optimize.leastsq, are twice as high than the Monte Carlo simulations.
This affect model fitting, and the calculated chi2 value.

Left column is 2000 Monte Carlo, right column is scipy.optimize.leastsq.
