just adding antitrigger SF in 2D (for effSyst in dilepton analysis)
This PR only modifies allSmooth_GtoHout_vtxAgnIso.root with the 2D eta-pt SF, usually needed only to derive effSyst (nominally we use 3D SF stored elsewhere), and only adds a few missing histograms with anti trigger SF. All the rest is unchanged (and I tested locally that the histmaker scripts run successfully).
