This MR mostly changes the following things:
1: Adding the option figsize
to the plotting configs for the ROC curves
2: Erasing the ttbar only files from examples (redundant)
3: Adjust the Preprocessing config to new Preprocessing
4: Fixing a small doubling bug in the Preprocessing config from DESY
5: Clean the plotting eval config from dips a little bit
6: Adding a colorbar title to Saliency Maps for Dips
