This commit adds a new stream stats endpoint which can be used to retrieve the fps metrics in a way that doesn't affect performance.
This commit ensures that the paths are also available under the `live` prefix. This will allow consistency with the hosted experience and improve the user experience.
This commit improves the naming of the parameters that are used in the fps calculation to ensure they are more descriptive.
This commit ensures that the video stream reference is removed from the app's `video_tracks` object when a stream ends, preventing potential memory leaks, incorrect data and ensuring proper cleanup.
This commit adds the frame delay between the processing time and the expected presentation time to the `/stats` endpoints.

This pull request adds the frame delay between the processing time and the expected presentation time to the
/statsendpoints.Current implementation
I calculate the delay between the expected presentation time and the processing time to get a metric for frame delay. This metric will be returned in the stats endpoint that was implemented in #48. It does not take the roundtrip time into account so it does not reflect full perceived latency. The response of the endpoitn will look like this:
{"913cf9e4-ab7d-4d4a-804f-5922793f5410": {"fps": 13.998930775037604, "frame_delay": 59.76668844101066}}Important
Merge after #48.
