get_mute, get_volume and set_volume

[giefca]

Your component is really fast compared to mine. If you want I've made modifications to yours to add my upnp commands to get volume and mute state in HA. You can test it and add it to your component if you want.

I've added your changes to my fork at: https://github.com/jaruba/ha-samsungtv-custom/

Other improvements:

• Voice assistant support (turn on / off, volume up / down, set volume to %, change input source to X)
• Key chaining: source_list: '{"TV":"KEY_SOURCE+KEY_LEFT+KEY_LEFT+KEY_ENTER"}

@jaruba thanks, I just saw your fork on ha forums and recognize my code in it. I will follow your work to see what features you can add. I managed to add music and video playback with the play_media service. I can make a PR on your fork if you want. I wanted to add notifications but I can't find a way to do it.

@giefca You mean you got play_media to work through DLNA casting? That would be interesting, as it might work with Voice Commands too..
