/// Each MSZIP block MUST consist of a 2-byte MSZIP signature and one or more RFC 1951 blocks. The
/// 2-byte MSZIP signature MUST consist of the bytes 0x43 and 0x4B. The MSZIP signature MUST be
/// the first 2 bytes in the MSZIP block. The MSZIP signature is shown in the following packet diagram.
///
/// Each MSZIP block is the result of a single deflate compression operation, as defined in [RFC1951].
/// The compressor that performs the compression operation MUST generate one or more RFC 1951
/// blocks, as defined in [RFC1951]. The number, deflation mode, and type of RFC 1951 blocks in each
/// MSZIP block is determined by the compressor, as defined in [RFC1951]. The last RFC 1951 block in
/// each MSZIP block MUST be marked as the "end" of the stream(1), as defined by [RFC1951]
/// section 3.2.3. Decoding trees MUST be discarded after each RFC 1951 block, but the history buffer
/// MUST be maintained.Each MSZIP block MUST represent no more than 32 KB of uncompressed data.
///
/// The maximum compressed size of each MSZIP block is 32 KB + 12 bytes. This enables the MSZIP
/// block to contain 32 KB of data split between two noncompressed RFC 1951 blocks, each of which
/// has a value of BTYPE = 00.
