Features

Easy installation: mlagents-video-streamer is now available as a python package on PyPI.
Dynamic streaming: The package can be used for a wide variety of streaming services by just providing URL and client secret.
Easy handling: start() & close() methods are given so users can start and close the video stream whenever they want.
Auto close: Now no need to manually kill the FFmpeg & Xorg subprocess.

Breaking Changes

videostreamer has been replaced with mlagents_video_streamer.
config() has been removed and SetupVirtualDisplay() has been added.
twitchStreamer() function has been removed and VideoStreamer class has been added as a more general form of streamer.
Previously twitchStreamer() only took secret key, but now VideoStreamer takes an dictionary (while initializing the class) in the following format only:
```
stream_info = {
"URL": "rtmp://live.twitch.tv/app/", # example of Twitch URL
"secret": "--- secret here ---"
}
```
start() method is provided by VideoStreamer class, so you have to call the start method on the object before starting the training process.
close() method is also provided by VideoStreamer class, & it can be used to close the video stream after training is done.
