Colour Sort

Generating Images using all 256³ RGB colours, inspired by https://allrgb.com/

Technique

To generate a re-coloured image, the source image's pixel data is sorted (using one of several different sorting modes) using numpy's argsort function, giving us a mapping from the original to the sorted version. This mapping is then used to "unsort" an array of all 256³ colours that in sorted order. The result of this operation is then written out as our result.
