chart cell contains : raw/comp ratio : encode mb/s : decode mb/s
LZB16: LZ-bytewise: super fast to encode & decode, least compression
LZNIB: LZ-nibbled : still fast, but more compression; between LZB & LZH
LZHLW: LZ-Huffman : like zip/zlib, but much more compression & faster
LZNA : LZ-nib-ANS : very high compression with faster decodes than LZMA
All compressors can be run at different encoder effort levels

vs LZMA :
ratio: 1.901
enc : 2.70 mb/s
dec : 30.27 mb/s
On this file, BitKnit is 13X faster to decode than LZMA, and gets more compression.
(or at "Normal" level, the ratio is similar and BitKnit is 4.6X faster to encode).
