huffyuvenc: add a non-deterministic option
...
Not actually used in huffyuvenc, but rather in setting the frame
threading.
Example for some files:

context=1,ND=0: 471819 22604 972351

huffyuv: change statistics initialization
...
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.
Output size of ffvhuff on various 4:2:0 sequences:
context=0,1/d: 851974 27226 1137281
context=0,1/d²: 619081 25069 1051500
context=0,1/d³: 501983 30454 1290561
context=0,lapl: 500650 31754 1304082

This is probably not the simplest solution but as this is needed for a bugfix,
simplification is left for later.

Almost all of the code is shared so there is little point in
enabling one decoder/encoder without the other.
