The platform has the ability to compress a byte vector using the LZ4 algorithm.LZ4 is a lossless data compression algorithm that is focused on compression and decompression speed.

Syntax: .o.compress <vec>; .o.compress[<vec>]

Decompresses a byte vector.

Syntax: .o.decompress <vec>; .o.decompress[<vec>]
