There was no screen display on macOS 12

I downloaded the latest jar package and successfully entered a chat room, but there was no screen display. Does it need any additional configuration?

Currently there are 2 issues:

1. This library is missing the macOS webcam support since it is not implemented by the WebRTC library itself. But there is demo code which has webcam functionality implemented. I will tackle this issue soon.
2. It seems the AppRTC protocol has changed this is why the demo is not working properly. The demo is just a proof of work of webrtc-java. I'm not sure whether to fix the demo code or not wasting time for that and rather extend and stabilize the library itself, like implementing macOS webcam support.

Same macOS camera issue as in #34
