📄 Description

Zstandard zips can be created with winzip. Zstandard 7zips can be created with 7zip here: https://github.com/mcmilk/7-Zip-zstd

This uses the nuget package from this git repo: https://github.com/oleg-st/ZstdSharp

As this PR uses an external nuget reference, I'm submitting it for reference. Should the zstd code be imported to SharpCompress?

Thanks.
