    Writes and reads alpha to and from the bitstream.
    A special case is needed on the encoder side to handle prediction block
    skips. Since whether or not a prediction block is skipped during CfL, a
    rollback is required if the block was skipped and the alpha index was
    not zero. The advantage of this is that no signaling is required when
    the prediction block is skipped as it is assumed tha the alpha index is
    A encode facade is added to the intra prediction facade as CfL requires
    special encoder side operations.
