LZ compression

LZ compression is a lossless compression algorithm that uses a compression dictionary to replace
repeated data in the same message. The compression dictionary is carried in the compression result.
The sending device uses the sliding window technology to detect repeated data.
Compared with DRE, LZ compression has a lower compression ratio. LZ compression does not
require synchronization of compression dictionaries between the local and peer devices. This
reduces memory consumption.
