Serve compressed content directly from zip file

[InsaneKnight]

Currently, this server seems to be always decompressing the requested file itself and serve the decompressed content to the client. However, as https://www.codeproject.com/Articles/30561/Using-ZIP-content-for-delivery-over-HTTP said, the compressed file contents within a zip file are already DEFLATE streams, so when the client requests Accept-Encoding: deflate, the server could directly serve the compressed content directly from zip file.
