Calculate and apply absolute scale correction for SANS data. The method used can either be a simple scaling using the ScalingFactor property, or computing the scaling factor using a reference data set. In this case, the reference data is loaded, normalized and corrected for detector sensitivity. The corrected reference data is then used to compute the scaling factor according to

$f = \frac{N_b}{M*T} ( d/L )^2$
