Kwabena W. Agyeman d6b49adefa Speed up lens_corr.
Speed up the algorithm by fixing the abs() issue. Do not use that
function in any of your code. It by itself cut the speed of the code
in half. I don't know what's in that function but I'm guessing it does
ABS of a float using ints or something.

I made the zoom parameter functional now too so you can use lens_corr to
zoom in on the image. Argument parsing is handled too. Finally, I
updated the only script where this is used.

Note that I'm able to get more than 10 FPS at 160x120 on the M4 and 15
FPS at 160x120 on the M7. Previous this was at about 5 FPS and 7.5 FPS
respectively.
