lz4 package

Provides stream classes for the LZ4 algorithm.

The block LZ4 format which only contains the compressed data is supported by the `BlockLZ4Compressor*putStream` classes while the frame format is implemented by `FramedLZ4Compressor*putStream`. The implementation in Commons Compress is based on the specifications "Last revised: 2015-03-26" for the block format and version "1.5.1 (31/03/2015)" for the frame format.

Only the frame format can be auto-detected this means you have to speficy the format explicitly if you want to read a block LZ4 stream via `CompressorStreamFactory`.
