      huffyuv: change statistics initialization · e7fc5d53

      Normally, a Laplace distribution is more typical of the residuals
      encoded, but for noisy input, it's both better and simpler to be
      safe and use a 1/d^2 distribution. Second hunk could use some
      renormalization but it has effectively little impact.
