streamAdvanceFromBest()

static void streamAdvanceFromBest ( DmtxEncodeStream * streamsNext, DmtxEncodeStream * streamsBest, int targetState, int sizeIdxRequest )

static

It's safe to compare output length because all targetState combinations start on same input and encodes same number of inputs.

Only difference is the number of latches/unlatches that are also encoded
