Thank for your analyse. It seems it's a corner case, benchmarking a base64 encoded random file is not a typical case. igzip has no more advantage above libdefl

Thank for your analyse. It seems it's a corner case, benchmarking a base64 encoded random file is not a typical case. igzip has no more advantage above libdeflate. It has only fast compression at the levels 0,1,2 but with mediocre compression ratio.
