Update zdc_sipmontile_reconstruction.py

Increased maximum hit energy in digitization for the  SiPM-on-tile ZDC from 200 MeV to 800 MeV.  This is necessary for proper reconstruction of photon showers, which can have a much larger maximum amount of energy per hit due to the showers being less spread-out than neutron showers
