Zstandard compression tools
Zstd, short for Zstandard, is a fast 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.

- Update to 1.3.4
* perf: faster speed (especially decoding speed) on recent cpus
(haswell+)
* perf: much better performance associating --long with
multi-threading
* perf: better compression at levels 13-15
* cli : asynchronous compression by default, for faster
experience (use --single-thread for former behavior)
* cli : smoother status report in multi-threading mode
* cli : added command --fast=#, for faster compression modes
* cli : fix crash when not overwriting existing files
* api : `nbThreads` becomes `nbWorkers` : 1 triggers
asynchronous mode
* api : compression levels can be negative, for even more speed
* api : ZSTD_getFrameProgression() : get precise progress
status of ZSTDMT anytime
* api : ZSTDMT can accept new compression parameters during
compression
* api : implemented all advanced dictionary decompression prototypes
