New results added: CART-based Combination

We updated the page with new results! Simone Bianco et al. were so kind to share their results of their 2010 Pattern Recognition paper titled “Automatic color constancy algorithm selection and combination”. These results are incorporated in our sections results-per-method and results-per-dataset. They also recomputed the ground truth of the reprocessed version of the Color-checker data set and made these available together with their results on this data set.
