[feat] Add zstd #251
Description
Describe the feature
New Content-Encoding is introduced: zstd. All browser vendors work on this feature and most support this feature already: https://caniuse.com/zstd
Why zstd? While it doesn't compress as efficiently as brotli, which we already have, it is significantly faster. It is faster and more efficient than gzip, which we have too.
zstd is added to node:zlib in v23.8.0, v22.15.0. Currently it is marked as "Experimental". We can test
if zstd-related functions are available in Node and provide this functionality conditionally. In a short while, it'll be in all supported Node versions.

Personally I already saw it in the wild. For example, it is implemented by CloudFlare servers.
