Zstd, short for Zstandard, is a lossless compression algorithm,
targeting real-time compression scenarios at zlib-level compression ratio.

Zstd can also offer stronger compression ratios at the cost of
compression speed. Speed vs. compression trade-off is configurable by
small increments. Decompression speed is preserved and remains
roughly the same at all settings, a property shared by most LZ
compression algorithms, such as zlib or lzma.
