Change MVA ID variable of electrons to post CMSSW 130X naming
Deals with #60 (closed) Hotfix to allow processing of nanoAOD v12 produced with CMSSW 130X.
(Includes minor comment for photon preselection and one typo fix in prepare output file)
Note
Naming convention for Run 2 ID : `mvaIso_Fall17V2_WPXX
Naming convention for Run 3 ID : mvaIso_WPXX
Where XX
is 80
or 90
.
Run 2 ID supports WPL (Loose) but this is not support anymore for Run 3.
