Add integral image functionality to enable massive speedup of Sauvola
Note that there are some very small differences to the output compared
to the basic algorithm, but this doesn't make much difference.
This is due to minor differences with the standard deviation
calculation throughout, and with mean calculation at edges, for reasons
I'm unclear about.
WIP integral image speedup. mean is working
Very WIP, but mean is perfect once full window is used
Integral version all working!
Remove debugging info
Organise code better
