zst 0.4-1 (amd64 binary) in ubuntu oracular

 This is an alternate tool for zstd compression, one that takes a lot
 less space than the official one. It also behaves in a way consistent
 with other Unix compressors: the level goes only up to 9, the original
 copy of the file is not kept, etc.
 .
 The executable can also replace gzip xz bzip2.
