Add Stereo Microphone Input

I'd love to see stereo microphone input added as an option (even if just for Nitro subs or boosted servers). It could be an option that has to be toggled on voice chat channels or can be toggled on/off by Nitro subs. Adding it as a toggle would keep audio bandwidth down since many people would likely not use it, and the bandwidth per channel could be cut so that overall traffic stays roughly equal.

I think this would be great for ASMR and playing around with L/R channels since some people might use one mic for two people and they would be more distinguishable this way.
