Adds request decompression and response compression to Hummingbird
let router = Router()
router.middlewares.add(RequestDecompressionMiddleware())
router.middlewares.add(ResponseCompressionMiddleware(minimumResponseSizeToCompress: 512))Adding request decompression middleware means when a request comes in with header content-encoding set to gzip or deflate the server will attempt to decompress the request body. Adding response compression means when a request comes in with header accept-encoding set to gzip or deflate the server will compression the response body.
