Draft: UFO/LCTopo dR matching for Xbb and mT(Higgs candidate, MET) variables

What does this MR do

1. Adds dR matching for UFO and LCTopo jets in the Xbb score calculation handled by SetupMonoHJetSelector().use_LCTopo_for_Xbb in the MonoHToolSetup.py. If there is no LCTopo jet within dR<1 the UFO combined Xbb score gets set to -99. Note that this only handles the Xbb score and not the SFs, when the calibration is available we will have to see how we can also get these into the code (not sure if there is already a tool to retrieve dummy SFs). If we go with this dR matching we will obviously lose some events in the low MET merged region because the UFO reconstruction efficiency is higher than for LCTopo but I don't think this is too worrisome. I did some simple plots for the zp500_dm200_dh50 sample
2. Removes some of the unnecessary code related to unsupported Xbb WPs (anti-topness = 0, 50, 100)
3. Adds two mT variables to the output. One is calculated using the resolved region Higgs candidate (leading 2 b-jets) and MET, the other is calculated using the large-R jet and MET. Technically we can already calculate mT from our outputs but this way it involves less work and is less error-prone

I'd suggest that we do a nominal only production (v08) for this. Maybe we can wait until after our talk in the jet calibration meeting to see if we should add additional information. What do you think? @changqia @jburr @atee
