    Signal delta loop filter level between superblocks · a4b27de4
    Cheng Chen authored
    For the first superblock, signal a filter level (6 bit).
    For other superblocks, signal the delta (3 bit) and sign (1 bit).
    To guarantee the delta can be represented by 3 bits, the search
    range of current superblock filter level is capped as
    curr_lvl = prev_lvl +- ((1 << 3) - 1)
