Possible to add Janus to Ustreamer

[zcopter]

https://github.com/pikvm/ustreamer/blob/master/docs/h264.md provides availability to output the mjpeg in h.264 which appears to be a solution to get the http (mjpeg) stream into homekit via home assistant (hass). Would be nice if when ustreamer is being installed it would make the pull including janus so the output stream can be made in h.264
