New Feature: Multiple Audio Inputs and Outputs

It would be useful to allow an additional audio input so that a person could, for instance, connect a midi interface alongside their microphone for use in discord chat. This would be helpful for people who would like to play instruments over Discord without the use of external software like VBCable and VoiceMeeter. An additional output would be nice too so that users could send the output audio directly to capture software or music production software as well as headphones so that they can hear what's being output.

This feature would greatly help more music oriented discord members and channels
