Code was doing binning before thresholding, so I switched it to do thresholding first, then binning.

My original intent was to have the threshold be the photon count required for a fit. So perhaps binning might be needed for a given pixel to make that photon count and get fitted. However in TRI2 a given threshold remains in effect no matter how much you bin.

The behavior now is if a pixel is thresholded out it won't be included in the binning. It's as if the TRI2 Window/Pre-processing/Extend under mask checkbox is off. This means the edge pixels don't get binned as much.
