Adding fiducial flags for detector/particle level Hgg phase space

Adding fiducial phase space pass booleans to base processor. See Table 2 in CMS-HIG-19-016.Everything is basically trivial except the $\mathcal{I}_\mathrm{gen}^\gamma < 10,$GeV. This refers to the sum of the energy of stable hadrons within the \Delta R = 0.3 cone of the respective photon.

To emulate this, I choose the hcalPFCluster variable at detector level.

At particle level, I use some truth references but so far, no good idea to implement the isolation cuts.
