This MR adds support for RNN based Tau ID in the TauSelectionTool (jira issue: ATLTAU-1607).
TauSelectionTool is now able to apply cuts on 4 new ID working points: JETIDRNNVERYLOOSE, JETIDRNNLOOSE, JETIDRNNMEDIUM, JETIDRNNTIGHT.
One could also apply cuts on the transformed RNN score (using JetRNNSigTransMin, JetRNNSigTransMax or JetRNNSigTransRegion). The interface here is equivalent to the cuts on the BDT score.
