feat: use AudioGraph to output and process audio
Use AudioGraph to handle audio output from VLC using audio callbacks. This change allows us to potentially extract audio data for additional post-processing and filtering, or external use cases such as audio visualizations.
As the AudioFrameInputNode has a limited buffer, a circular buffer is used to transport and package audio data from VLC into audio frames. VLC and AudioGraph run on separate threads, interacting with the buffer asynchronously. Due to the complex nature of the producer-consumer model, some audio issues can occur, including delay, click, or hitch.
