I decided to create a new AudioFramesOutput struct instead of relying on the existing FrameOutput, which contains unnecessary fields like streamIndex and durationSeconds. For now, those aren't needed for audio. No super strong opinion though.

I think that's the right call, since the tensors are going to be very different.

| frames.push_back(frameOutput.data); |

It's now a bit ugly that we are manipulating both a FrameOutput and an AudioFramesOutput here in this function.
This is mostly because convertAVFrameToFrameOutput returns a FrameOutput, but maybe we could bypass it and directly call convertAudioAVFrameToFrameOutputOnCPU. I'll write a TODO to investigate this.

Oh, yeah, that's cumbersome. If we're in an audio-only call, we shouldn't have to deal with video structures.

I thought we didn't need this, but we actually need it in order to implement the public sample-based API (which is out of scope for this PR).
