Stereo opus files sound glitchy when playing back.

[pixlwave]

Steps to reproduce

1. Upload one of the sample files from https://filesamples.com/formats/opus to a room from web.
2. Open the room on iOS
3. Play the file back.

Outcome

What did you expect?

The file to sound the same as it does on desktop.

What happened instead?

It sounds very glitchy and reports as being twice the length it should be.

It looks like the SwiftOGG package is forcing kAudioChannelLayoutTag_Mono instead of reading this from the file.

Tried a bunch of things to fix this including playing with channels and interleaving. Haven't found something that addresses the crackling.
