Expand the list of supported monitor models for volume control via DDC

Short summary

Control external monitor

Why is this needed?

I bought the app hoping I could control the monitor audio output directly through my keyboard dedicated keys, but the Samsung M9 monitor isn't supported yet. I hope this feature will come in the future.

Proposed solution / behaviour

By pressing volume up, down or mute, the audio output increases, decreases or is muted.
