- Fixed drawing of round objects (Circles, Rounded Rects) using a lookup table

- Added function to read out the display_buffer via USB-Serial
 - Added basic structure and files for later complete firmware (still in progress)
 - Added Doc folder with schematic in it
 - Added Python script and batch file to read out the display buffer and open the image in gimp
