25     - a length (number of bytes to copy from dictionary)
26     - the number of literals to copy, which is retained in variable "state"
53   ranges, resulting in multiple copy instructions using different encodings.
57   After any instruction except the large literal copy, 0, 1, 2 or 3 literals
66   End of stream is declared when a block copy of distance 0 is seen. Only one
81                 noting that codes 16 and 17 will represent a block copy from
85       18..21  : copy 0..3 literals
86                 state = (byte - 17) = 0..3  [ copy <state> literals ]
89       22..255 : copy literal string
91                 state = 4 [ don't copy extra literals ]
98         If last instruction did not copy any literal (state == 0), this
99         encoding will be a copy of 4 or more literal, and must be interpreted
102            0 0 0 0 L L L L  (0..15)  : copy long literal string
106         If last instruction used to copy between 1 to 3 literals (encoded in
107         the instruction's opcode or distance), the instruction is a copy of a
110         bytes to encode a copy of 2 other bytes but it encodes the number of
113            0 0 0 0 D D S S  (0..15)  : copy 2 bytes from <= 1kB distance
115            state = S (copy S literals after this block)
119         If last instruction used to copy 4 or more literals (as detected by
120         state == 4), the instruction becomes a copy of a 3-byte block from the
123            0 0 0 0 D D S S  (0..15)  : copy 3 bytes from 2..3 kB distance
125            state = S (copy S literals after this block)
134            state = S (copy S literals after this block)
142            state = S (copy S literals after this block)
146            state = S (copy S literals after this block)
153            state = S (copy S literals after this block)
