add some functions for arducam. i had to move ArduCAM folder to hardware/sam/libraries in order to prevent extensive changes to my makefile. also i had to change ArduCAM.cpp to include Wire/Wire.h and SPI/SPI.h instead of Wire.h and SPI.h
using lisp i can read +mask-shutter+ back, when i press the the button on the arducam
i forgot cam-read-fifo
i made all the delays in the serial communication functions as small as possible but sending the data takes ages this way
insert usb-write-bytes-from-fifo, a function that will hopefully send the image data over the usb port
