Message:

updates to pmPeak to better distinguish peak flux versions; updates to visualization; add bits for substantial suspect masking; consolidate assignment of source position and flux based on peak, moments, etc; improve footprint culling process; fix PSF_QF and PSF_QF_PERFECT calculations; fix source model chisq values
