zstd is a very good compression algorithm. In recent years, it has been used by more and more open source projects. Recently, the zstd compression algorithm has been added to the zip compression specification. The magic number is 20. Now, I suggest that minizip start to add support for zstd .

I use minizip as the implementation of baulk's zip decompression function, and currently implements a zstd support that has not been sufficiently tested for reference:

Follow-up of other compression software:
mcmilk/7-Zip-zstd#132
p7zip-project/p7zip#25
mholt/archiver#223

Thanks.
