This pull request completely rewrites how gateway compression works and adds zstd support. Previously, gateway compression went through a PayloadDecompressor pulling the current compression mode from the configuration; now we register a different compression service based on the determined compression mode. This supports a default selection as outlined in the new documentation; attempting to load zstd and falling back to zlib if zstd is unavailable.
This pull request improves zlib performance somewhat, especially zlib-payload (which is no longer a default-recommended option due to its many shortcomings as payload-wise decompression). Zstd performs considerably better due to not needing to copy memory or make temporary allocations beyond what the native implementation requires.
