* Tweak compression settings zstd: Limit window sizes to 128K to keep memory in control both server and client size. zstd: Write 0 length frames. This may be needed for compatibility. zstd: Create fewer encoders. Small memory improvement. gzip: Allow -2 (Huffman only) and -3 (stateless) compression modes. * Update modules/caddyhttp/encode/zstd/zstd.go Update docs.
