Update to PanCam filter graph
Okay, finally JPL posted how to read the filenames on raw images, as if we need it now thanks to Robert.
But looking at this I find that the table I used to assemble my filter graph was old, and therefore I need to tweek some of these filter values by a handfull of nanometers here and there. I'll do so and repost if I've the time and if there is interest.
