Calls the LZ4_compress C function. Returns a S8-Vector containing the compressed data in LZ4 Format.[procedure] (compress-hc s8vector)
Calls the LZ4_compressHC C function. Returns a S8-Vector containing the compressed data in LZ4 Format. This procedure uses the high compression variant of LZ4.[procedure] (uncompress s8vector)
