adding "no data" value and color for that value #58

ISCE2 interferograms (unw) have the "no data" phase value as 0.0. It would be useful if there was a way to tell "qed" to take all pixels with phase value 0.0 as "no data". In this ISCE2 interferogram, the large areas of purple color are the 0.0 phase that should be "no data".

Setting the "no data" pixels to transparent is a good option. It would be even better if "qed" allowed the color of "no data" pixels to be chosen, like QGIS allows.
