[indomitableMan]

Added new AdjustVolume action to support using a StreamDeck+ Encoder to adjust volume and mute Sonos system.

Did you create an Icon and didn't commit it?

(Also, THANK YOU FOR THIS)

The icon is one of the existing material design icons that this plug-in already uses. However as noted elsewhere this code is not 100% functional due to a library conflict. I need to perform further work on this code to get it working properly.

@indomitableMan Let me know if you're still working on this and need a tester. I just upgraded to the Stream Deck + today so I can now help beta test.

[indomitableMan]

I am not currently doing any further work on this plug-in. Due to the library conflict and a couple of architectural issues, I think I will start on a new Sonos plug-in exclusively for the Streamdeck+ after the new year.

Ok sounds good. Let me know if I can help sometime in the new year with testing.

@GenericMale Is there anything left to do on this plugin where it would be able to get merged?

@indomitableMan otherwise, would you be willing to send your built elgato file? I don't have a windows machine to bundle things.
