Zhuff

Zhuff is a compression software designed for speed (especially decompression speed).
It is based around LZSS & Huffman mechanisms, similar in principles to Zip.
Schematically, it consists of LZ4 & Huff0 merged together.

Zhuff is typically 4 to 5 times faster per core than Zip's fastest mode.

Zhuff also proposes High Compression modes (-c1 and -c2), using MMC match search algorithm, which will trade some CPU cycles for more compression. See benchmark results below.
