This MR contains a few updates to the MuonSelectorToolsTester:
Add Low-pT working point with MVA option as an additional working point
Add author information both in the text output for each muon and in a new summary table
Use the truthType decoration on the muon instead of running MCTruthClassifier, since MCTruthClassifier cannot work with the reduced truth content in DAOD_PHYS
Add a unit test to process the ASG_TEST_FILE_MC (we ran only data before)
