Zstandard compression

Zstandard is a general-purpose lossless compression algorithm. Zstandard, or zstd as short version, is a fast lossless compression algorithm, targeting real-time compression scenarios at zlib-level and better compression ratios. It's backed by a very fast entropy stage, provided by Huff0 and FSE library. It often offers better compression ratios than brotli at equivalent CPU costs, or better CPU costs at equivalent compression ratios. For browser support, see Content-Encoding: Browser compatibility.
