PR-Overflow Warning Fixes
This PR fixes the following warnings:
overflow encountered in sinhoverflow encountered in coshinvalid value encountered in _mass2_kernel
These warnings appear as a result of lead_jet or sublead_jet being assigned unphysical values (pt,eta,phi,mass,charge). The issues arise when during the operation 'dijet = lead_jet + sublead_jet' as a result of how coffea handles the operation i.e. adding the 4-vector components in cartesian coordinates i.e. lead_jet.z will yield an unphysical result which spits out warnings. This is now mitigated by setting the unphysical pt,eta,phi,mass,charge to zero instead of -9999.0 and doing the operations on the newly formatted lead_jet and sublead_jet, and when storing results such as dijet.mass or dijet.pt, the events with unphysical values to begin with, are assigned the default -9999.0 values as expected.
