Talking feature

[MuhammadjonTohirov]

Are you talking, I just extracted audio level from rtc statistics, it's up to developer to implement are you talking feature. There is a delegate func audioLevelChanged(_ client: AntMediaClient, audioLevel: Double, hasAudio: Bool), and this method should let developer to know that audio level and it's status. if audio level has some value and hasAudio is false, it means that use muted the mic and tring to speak

Hi @MuhammadjonTohirov,
I would like to congratulate you. This PR has much more better from the previous one.
Here are the points that I see as improvement

• You've updated the .gitignore
• You've removed the local files that I sent previously.
• You've made your branch up to date.
• Your PR focuses on a specific feature then it's easy to merge/review

Things to improve

• It seems you deleted project.pbxproj which is required to open the project. Please correct me if I'm wrong
• I've added comment for the audioLevelChanged method to make life easy for developers
• I've invalidated timer in registerAudioLevelExtractor to not encounter multiple timers run at the same time accidently.
• I've let the developer manage registerAudioLevelExtractor/removeAudioLevelExtractor with his own timeInterval

Please let me know if you think differently or you have feedbacks/forwards for me

Thank you, Cheers
