31 state->bits < 8
32 (state->hold >> state->bits) == 0
48 - The maximum input bits used by a length/distance pair is 15 bits for the
49 length code, 5 bits for the length extra, 15 bits for the distance code,
50 and 13 bits for the distance extra. This totals 48 bits, or six bytes.
54 - The wide input data reading option reads 64 input bits at a time. Thus,
58 hold |= read64le(in) << bits;
60 bits += 48;
62 reporting 6 bytes of new input because |bits| is 0..15 (2 bytes rounded
64 hold &= (1U << bits) - 1 drops excess input to keep the invariant:
