lluisemper b8e643259e zlib: add dictionary support to zstdCompress and zstdDecompress ...

Adds optional dictionary support to zlib’s zstdCompress and
zstdDecompress APIs. This enables better compression ratios when the
dictionary matches expected input structure or content patterns.

The implementation allows passing a `dictionary` buffer through the
options object. Support was added to both streaming and convenience
methods. Tests and documentation were also updated to reflect this new
capability.
