boost::gil::non_overlapping_interpolated_clahe

Performs local histogram equalization on tiles of size (tile_width_x, tile_width_y) Then uses the clip limit to redistribute excess pixels above the limit uniformly to other bins. The clip limit is specified as a fraction i.e. a bin's value is clipped if bin_value >= clip_limit * (Total number of pixels in the tile)
