Ability to Pan audio streams left-right, like on TeamSpeak

I'm super fan of your module thank you so much!

One thing I really think that would improve the experience, is to be able to recreate your "table" by freely moving the voices of each participant, from left to right, like you can do on TeamSpeak using the 3D audio mixer.
I don't think the whole 3D spectrum is that needed at all, but being able to move voices away from each other, instead of being all right at the center, makes conversation much easier, because our brain can follow the different lines, even if someone were to talk over another one. Just like a normal real-life conversation with your friends.

Is it something possible to do? Just a very basic control on each window, from -100 to +100, or even -10+10 would suffice.

The issue body is the only implementation reference provided and does not name files or tests. Start by locating the participant audio-stream and participant-window UI entry points, then determine whether each stream exposes stereo panning. Done means participants can be positioned left or right with a bounded control and the setting audibly separates voices without breaking existing playback.
