Optical loading

As the final event file does not contain events below 150 eV, the information to assess the presence of optical loading in a straight forward way is not available in the event file anymore. Parameter optloadingimage therefore controls the optional creation of an image in the ADU 20–30 range where optical loading is easily visible.
