Description

Currently, we divide single- and multi-PLD quantification in step 8 of the ASL module (Perform Quantification) and perform the preprocessing steps twice. For future code changes we need to merge this together and perform the specific single or multi PLD quantification steps a layer down (follow-up issue to #759). Furthermore, all scaling can be in separate function, so we might as well do this in a separate function.
