Add Zstandard compression support.

Browse Source 
Zstandard 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.

Zstandard version >= 1.0 is required, which is generally only available on newer distributions.
