Add monitoring for SMOG PVs
As part of a bigger effort to include monitoring for SMOG2, this MR adds the monitoring of the number and the z for PVs reconstructed in the SMOG2 region, with the same strategy as done for pp.
Since in principle we can foresee both a la SMOG and a la SMOG2 injections, the histogram limits are set automatically based on the injection type. Branch is tested on a private simulation, with the resulting histograms being for the number of SMOG2 PVs and for the z distribution
