1.8.0

We've added a mixing feature to enable the use of different audio sources. Since it's still in beta, please provide feedback. It can be utilized by following these steps.

FeatureUtil.setEnabled(for: .multiTrackAudioMixing, isEnabled: true)

stream.append(sampleBufferA, track: 0)
stream.append(sampleBufferB, track: 1)

Internally, I am now handling data with more than 3 channels. If you encounter issues with IOStreamRecorder, it is recommended to set it back to a maximum of 2 channels when saving locally.

let channels = max(stream.audioInputFormats[0].channels ?? 1, 2)
stream.audioMixerSettings = .init(sampleRate: 0, channels: channels)

Also made the following changes:

1. Updated the minimum supported OS version.
2. Reviewed the API design to handle audio data from different sources.
3. Improved compatibility with RTMP.
4. Enhanced performance of SRT.
