   - correct RMS value calculation
   - issue #111: introduce a new -x (--serve_only) commandline switch for the cli. If -x is present no SSDP discovery is run and playing is not started. swyh-rs-cli just sits there waiting for play requests from renderers. Some other useful options in this use case are: -f (format), -b (bits) and -s (sound source).
   - CLI: boolean options no longer need an argument, absent means false, present means true. You can still use false to disable options stored in the config. The options -h, -n and -x are not stored in the config file.
