Invert nighttime Meteor M2 images.

I've added piece of code to invert Meteor M2 images from nighttime pases (APID68 from IR sensor) so that clouds appear white and not black, text overlay (satellite name, timestamp and elevation) on Meteor M2 images like NOAA have, and deleting all intermediate images.
