Allow to change between Wired and Wireless modes (KEF LSX & KEF Wireless II)

[ecruz1986]

KEF LSX and KEF Wireless II support both wired and wireless mode between the two speakers.

Just plugging/unplugging the cable won't automatically make it switch from wireless/wired mode. We have to use the KEF Control app, go into Settings, Preferences, and then tick/unitck the wired mode option.

It would be nice if this option is added to kefctl.

I don't have either devices for testing, so i can't add the feature.

I've got the KEF LSX. I will try to get familiar with the kefctl code and sniff some packets, maybe I can implement this myself and submit a pull request, but I can't promise it!
