[kpedro88]

@kpedro88 submitting this PR for @lgray. Cuts on delta_pt/pt were added for the Pandora PF objects to reject misreconstructed tracks. These cuts had the desired effect of removing jets/charged hadrons with unphysically high energies.

Please include this PR in the release with the other HGCal Pandora PRs. This is important for physics performance.

As well as the automatic tests, I tried 15600 and 15800 (Pandora reconstruction for 0 and 140 pileup respectively). 15600 completed fine, 15800 failed but it was xrootd errors on the minimum bias files, which I'm going to assume is transitory.
