20 The stream is composed of a series of instructions, operands, and data. The
21 instructions consist in a few bits representing an opcode, and bits forming
26 - a distance when copying data from the dictionary (past output buffer)
27 - a length (number of bytes to copy from dictionary)
28 - the number of literals to copy, which is retained in variable "state"
29 as a piece of information for next instructions.
32 extra data can be a complement for the operand (eg: a length or a distance
33 encoded on larger values), or a literal to be copied to the output buffer.
35 The first byte of the block follows a different encoding from other bytes, it
