Simple CLI demo for MacOs running agains mediasoup-demo

[jmillan]

Basic CLI demo:

• Connects to a mediasoup-demo server via WS as a browser client does.
• Produces audio and video.
• Consumes remote participants media (no rendering).
• Creates DataProducer|DataConsumer.
  • Prints the received messages via DataChannel.

As an example, this is the output you'll see when running the app:

[room] connected
[room] device loaded
[room] joined
[send] connection state changed to: checking
[send] connection state changed to: connected
[send] connection state changed to: completed
[recv] connection state changed to: checking
[room] consuming audio from erztw5ev
[room] mic producer: 4b8af09a-f1ab-4cbe-afc3-d7dbfe36621f
[recv] connection state changed to: connected
[recv] connection state changed to: completed
[video] camera: MacBook Pro Camera
[room] consuming video from erztw5ev
[demo] video track from erztw5ev
[data] Welcome mediasoupclient-demo! ☺️
[video] camera started 640x480@30fps
[room] camera producer: 3fa1a8c6-43a5-4431-b3f1-d10653bfb783
[room] chat data producer: b8003f93-544a-4d3a-806e-e280de63e52d
[demo] running — press Ctrl+C to quit

Sets the foundations for a more elaborated app.

NOTE 1: This is merely a testing app so we can test the library against our demo.
NOTE 2: The demo is inside the libmediasoupclient repo on purpose, so we can run the app and test the library as we develop it.

Once this is merged, we can remove mediasoup-broadcaster-demo which is unmaintained and most probably not working, and use this app instead, which connects as a regular user.

NOTE 3: I may probably stick to Listener callback pattern all around. In some places I'm passing callbacks in constructor arguments, and in some other I'm passing the parent object to the child does parent.onFooBar() which is not nice.

If it prints messages received via DataChannel why am I not seeing the "Hello xxx" message?

Sorry, do you mean that you have created a built-in demo server in Rust within this PR?

What 😀?? No, this demo app resides in libmediasoupclient repo for the reasons given. It connects to the existing mediasoup-demo via WS, as browsers do.
