Tests:

compress fflate
// The default compression method is gzip // Increasing mem may increase performance at the cost of memory // The mem ranges from 0 to 12, where 4 is the default fflate.compressSync(buf, { level: 6, mem: 8 });

decompress lz-string

decompress shorty
shorty.inflate(shortyCompressed)
decompress fflate
