randomizing discovery responses and adding tradfri

[thexperiments]

the order of the discovery responses is now randomized so it should be a bit easier to add more than 16 devices with a few searches through the echo (worked great for me)

I also added the tradfri lights, works great.

Thanks for the plugin.

Thanks for your contribution! I see if i can ultimately fix the device limitation with #14. But for now, your changes are great.

Sure would be better. I think what I did is just a hack but it worked quite well for me. I don't know if multiple upnp listeners would help maybe you could test this with two instances of pimatic running with 16 devices each and ask the echo to search for devices. For my setup I always get "I found 16 smart home devices" when triggering via voice so this is a better indicator than the app.
