Histograms showing number of cluster/tracks discarded by cuts

The 'cut flow histograms' are currently only implemented for DUTAssociation and for AnalysisDUT. We could add them to other modules as well if needed.

Please have a look at the naming of the histograms and let me know if you have other suggestions. I tried to find a trade-off between having a descriptive title while being concise but I'm not 100% satisfied with it.
