Support for Zstandard

[acecilia]

Hi 👋

Thanks for such a GREAT library 🎉
Wanted to ask about Zstandard support.

I see that p7zip supports Zstandard.
I tried to extract a file with PLzmaSDK from an archive created with -m0=zstd, but it failed.

Do you have any plans for supporting it?

Thanks again

Hi,
since a lot of time, the original/underlying LZMA(ver. 24.06) code contains Zstandard decoder without external FB lib.
Without Zstandard encoder - it's a partly implemented feature.

P.S.: the version 24.06 will be patched soon in feature ver. 1.5.0.
