Box lights algorithm first commit

box_fft.py: Algorithm to detect box light centers and frequencies
	bounding box method
	scan boxes at 5 places for freq changes and vals
	move slope along box finding best fit
	split boxes and find COM centers
	return freq and position of centers

aoa.py: allow return False on brute force k algorithm
aoa_full.py: accepts false from brute force k
error_list.txt: updated saved values
freq_list.txt: updated saved values
opencv_fft.py: implemented decisions for box light vs circle
box.py: new room measurements for box light
test.py: integrated box light testing
test_pics.py: added box light images to list
