Add "Speaker" as device type

[Joennuh]

Hi!

I just discovered this Node-RED node and already have so much fun with implementing and using it!

Yesterday I made my old Onkyo receiver a bit more smart with the help of this node. I did that by choosing the device type "Light" and link the brigtness of the "Light" device type to the volume of my receiver. For voice commands this is a bit inconvenient and so I was wondering whether it is possible to add "Speaker" as device type to the node. Or does anyone has any other great suggestions to improve the ease of voice command operation to my non-smart Onkyo receiver?

I've not got much time to add features at the moment, but I'll add it to the list.

Would need to work out what traits to support for a valid speaker.
