-Experimental converter that transforms standard png, jpg and bmp files to useable bmp files which can be used by the Calendar.

-## What this script does:
-# grab images from one folder, perform some operations and paste them in an output folder.
-# The operations consists of removing the alpha channel, reducing the colours to (currently) just two,
-# Inverting the colours (as the display inverts them again) and rotating the picture by 90 deg clockwise
-
-## Please only use png files for now as that has been tested and confirmed to work so far.
