Reducing saturation (band-average pixel values) for pixels with very low noise should remove this, but may have some unwanted consequences for the galaxy.

Major progress - added desaturation based on pixel signal/noise from estimated photon counts. Needs to be finalised after colours set in sensible way.

The desaturation code is a bit messy
