    * code the palette color index using 45 wavefront
    * interleave the coeff and palette color index in
      transform block level
    * the above change does not change code efficiency
    The 45 wavefront scan allows to compute the ctx of
    the diagonal samples' indices  at the same time. 
    Interleaving palette indices and palette residual
    on a transform block basis means that the entropy
     decoding and further processing of the palette 
    residual is not delayed by the entropy decoding 
    of all the color indices of the palette encoded
