Image index lookup

Takes an integer image and perform a table lookup against a table indices. It maps each integer value in the input image against the row that has that index. For each non index column in the table it creates one channel of output data with the value at that row. colums in that row it creates one channel.

Can be used for palette lookup or for operating on superpixel labels.
