this MR does several small updates to the FTag Physval code.
The comparison plots with and without the code changes show perfect agreement, except for the IP3D d0 and z0 significances, where I changed the range: https://juhofer.web.cern.ch/juhofer/PHYSVAL/test_plots/test_MR_2021-05-04/
The commit juhofer/athena@81404070 is the quick fix for the issue reported here: AFT-555.
The code now runs on the Sherpa sample without crashing (histograms produced and compared to themselves are here: https://juhofer.web.cern.ch/juhofer/PHYSVAL/test_plots/test_MR_2021-05-04_Sherpa_sample_test/plots/)
The code was also tested on a private DAOD_PHYSVAL sample, the plots can be found here (histograms are compared to themselves again): https://juhofer.web.cern.ch/juhofer/PHYSVAL/test_plots/test_MR_2021-05-04_on_DAOD_PHYSVAL/plots/
