Expand Audio Meter Configuration

I just checked out this feature and I love it. I mapped my macro keys on my Blackwidow Chroma v2 as a vertical audio visualiser using it, although there are certain things I'd really like:

1. Select the audio device
[indent]Even if this isn't per-key (just one device for any preset), it would still be incredibly useful for people who use multiple sound outputs or software like Voicemeeter[/indent]

2. Select Input devices
[indent]Being able to link this to my microphone input would probably make this one of my favourite things about chroma. Having an audio meter monitoring mic levels would not only look incredibly cool, but be genuinely useful for people like me who adjust their mic volume and need to make sure it's at a good level
[/indent]
Overall this feature is definitely awesome, but it's also definitely not perfect, but these improvements would absolutely bring it to the next level.
