Function InverseMoveToFrontTransform

Transform: 1) initialize list L with values 0, 1,... 255 2) For each input element X: 2.1) let Y = L[X] 2.2) remove X-th element from L 2.3) prepend Y to L 2.4) append Y to output In most cases max(Y) <= 7, so most of L remains intact. To reduce the cost of initialization, we reuse L, remember the upper bound of Y values, and reinitialize only first elements in L.
