Add DiElectron lines to master
Thanks to @rjhunter for pointing out that the line was not imported in hlt2_qee.py. It now is. The lines have also been rewritten.
The original MR where these lines were added is here: !1365 (merged)
The new HLT2 lines select pi0 and eta -> e+ e- gamma candidates, building on the new HLT1 line to do the same. In fact they find an e+ e- pair worth triggering on, and then persist photons in a container where the combination of dielectron and photon yields an acceptable candidate. Here 'acceptable' principally means that the invariant mass of the combination lies within some useful range for the pi0 and eta studies.
Lines to be added to master are:
- Hlt2QEE_DiElectronPrompt_PersistPhotons
- Hlt2QEE_DiElectronDisplaced_PersistPhotons
- Hlt2QEE_DiElectronDisplaced_PersistPhotons_FULL
- Hlt2QEE_DiElectronPrompt_PersistPhotonsSS
- Hlt2QEE_DiElectronDisplaced_PersistPhotonsSS
- Hlt2QEE_DiElectronDisplaced_PersistPhotonsSS_FULL

where the prefix "Hlt2QEE_DiElectron" has been removed from each line name in the table to reduce with. HLT1-filtering on the fly means HltEfficiencyChecker ran both HLT1 and HLT2 over non-HLT1-filtered min bias, requiring a HLT1 filter on any of:

Yes, the big ones are big and yes, I'm confident in them. In the case of the 500 kHz one; this line has a retention of around 33% on that sample.
