setAudioMixingPlaybackSpeed abstract method

@Deprecated('Deprecated since v3.54.1, use RTCMediaPlayer.setPlaybackSpeed instead') Future<int?> setAudioMixingPlaybackSpeed({ required int mixId, required int speed, })

Sets the playback speed of the current audio file.

speed: Ratio of playback speed to original speed in percentage. The range is [50,200], the default value is 100.
Settings outside the range of values will fail and trigger RTCVideoEventHandler.onAudioMixingStateChanged.

Notes:

• You should call this API after calling RTCAudioMixingManager.startAudioMixing and receiving RTCVideoEventHandler.onAudioMixingStateChanged indicating that the AudioMixingState is playing and the AudioMixingError is ok.
  
• If you call this API after calling RTCAudioMixingManager.stopAudioMixingor RTCAudioMixingManager.unloadAudioMixing, you will receive RTCVideoEventHandler.onAudioMixingStateChanged indicating that the AudioMixingState is failed and the AudioMixingError is idNotFound.
