patch adding cvclahe element
Patch attached which adds cvclahe, an OpenCV element which applies contrast
limited adaptive histogram equalization
(https://en.wikipedia.org/wiki/Adaptive_histogram_equalization) to RGB, GRAY8,
and GRAY16_LE video.
This is useful to bring out detail in high dynamic range scenes. While it
provides interesting results in RGB and GRAY8, it is most useful in GRAY16_LE
video.
