Module encoder 

Available on crate feature deflate64 only.

Streaming PKWARE deflate64 encoder.

Structurally mirrors the RFC 1951 deflate encoder: 64 KiB sliding window with LZ77 (hash-chain match finder, optional lazy matching) feeding length-limited dynamic Huffman coding. Per block the cheapest of stored / fixed / dynamic is selected.

Compared to deflate the alphabet is widened: length code 285 now addresses matches up to 65538 bytes via 16 extra bits, and the distance alphabet uses the full 32 symbols so back-references span the entire 64 KiB window.
