Fixes and a few additional helper functions

- corrected the return type of a few functions to int
- Add DFWINDOW.TOOLS.getImageDiff to get how diff 2 images are
- Added complimentary lastNotBlack(X/Y)
- Increase blindly chosen preset "bottom_to_ignore". Wasnt enough when full screen.
- Fixed the sign/polarity of step sizes
- First attempt at calculating the size of the map. Probably wrong. Will replace when writing the map maker
- removed cv2.Stitcher stuff. Not what I needed
- Added some test_ functions for experimenting. Ignore.
