• Updated HeyGenVideoService and HeyGenTransport to support both HeyGen APIs (Interactive Avatar and Live Avatar). Using them is as simple as specifying the service_type when creating the HeyGenVideoService and the HeyGenTransport:

  heyGen = HeyGenVideoService(
      api_key=os.getenv("HEYGEN_LIVE_AVATAR_API_KEY"),
      service_type=ServiceType.LIVE_AVATAR,
      session=session,
  )
