Add event to receive raw PCM16 Audio

[AnasMations]

We are adding a face to Vapi's AI agent but there is a limitation:
We want to be able to receive raw PCM16 audio bytes to pass that to our facial animation model.

We have a similar need actually. We are not displaying a face, but we'd also like to be able to show an animation of sorts to visualize the agent speaking.

 public getDailyCallObject(): DailyCall | null {
    return this.call;
  }

we expose vapi.getDailyCallObject() now. to unblock yourself, recommend getting the raw pcm from there
