I've experienced issue when I put in +2 timezone, the script calculates sun elevation for -2 timezone so i changed plus to minus in time.localtime function. Also added support for Daylight saving time.

I've added elevation on text overlay, changed all images from JPG to PNG in order to preserve whole resolution and added code to remove map image for overlay.

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.
