Added new output file rule for ppImage: PPIMAGE.OUTPUT.DETREND. It differs from the usual PPIMAGE.OUTPUT only in the choice of compression. The idea is that for images with a fair gradient across them (like our new flats), we want to force the choice of bscale=1,bzero=32768, because the standard deviation of the image doesn't provide a good basis for choosing these. This file rule should now be enabled for detrend types that signal a fair bit of light in the process and residual stages.
