Add sst and tts capabilities to agent

[YujohnNattrass]

Agents now have a voice property with a composite voice type which allows the agent to have different providers for its voice capabilities.

Here is an example of what it would look like to initialize:

export const chefAgent = new Agent({
  name: 'Agent',
  instructions: `You are capable of speech to text and text to speech`
  model: openai('gpt-4o-mini'),
  voice: new CompositeVoice({
    speakProvider: new ElevenLabsVoice(),
    listenProvider: new OpenAIVoice(),
  }),
});
