+- Added `audio_out_insert_silence` parameter to `TransportParams` (defaults to `True`). When set to `False`, the SmallWebRTC transport waits for audio data instead of inserting silence when the output queue is empty, which is useful for scenarios that require uninterrupted audio playback without artificial gaps.

When set to `False`, the transport waits for audio data instead of inserting silence when the output queue is empty, which is useful for scenarios that require uninterrupted audio playback without artificial gaps.
