Implement ZSTD as a middleware for compression

[Kumzy]

Implement ZStandard library to compress data.

Media type: application/zstd

On our current API (flask), we implemented ZSTD to compress huge JSON response that were over 5MB using the default compression level (3) and resulted in some ~200Kb JSON. We use it for customers that have slow networks/low bandwidth.

As it's not native/supported by browsers, I do not think it can be used to compress html.

What library are you currently using for this?

We are using https://pypi.org/project/zstandard this one but it seems that a lot of python implementation of zstd exists
