Add KSVeloLongEfficiencyMonitor
This MR adds an algorithm which allows to plot the efficiency of adding SciFi hits to long tracks determined by a tag-and-probe implemented by @pherrero and @ldufour .
The efficiency is presented with profile histograms. There are 1D histograms for the efficiency as function p, pt, and eta and 2D histograms of efficiency versus eta,pt and eta, p. The axes of the histograms are configurable.
Needs !3784 (merged) and needed for Moore!3143 (merged) .
