Subject: [PATCH] fix(actix): use gzip level 1 instead of default level 6

The Compress middleware uses gzip level 6 by default, but the benchmark
spec requires level 1. Manually compress with flate2 Compression::fast()
(level 1) in the compression handler and set Content-Encoding: gzip so
the middleware skips re-compressing.
