liblz4-jni binary package in Ubuntu Focal amd64

 LZ4 compression for Java, based on Yann Collet's work available at
 https://github.com/lz4/lz4. This library provides access to two compression
 methods that both generate a valid LZ4 stream: fast scan (LZ4) with a low
 memory footprint, very fast and reasonable compression ratio, and high
 compression (LZ4 HC) with medium memory footprint, rather slow and a good
 compression ratio
 .
 The streams produced by those two compression algorithms use the same
 compression format, are very fast to decompress and can be decompressed
 by the same decompressor instance.
 .
 This package contains the architecture specific Java native interface part.
