Lumi plots in comparefits?

Created by: voisey

Could it be worth having a few lumi plots in the standard comparefits report, e.g. the flavour combinations we already have implemented at 13 TeV? It seems that these are often requested by people immediately after looking at a comparefits report so they could be quite useful and save some time. If you think it's a good idea I'd be happy to implement it.
