Show duration and time remaining for videos

**Is your feature request related to a problem? Please describe.**
When playing videos through the score system it is necessary to give signals to the video operators, emcee, and others for how much time is left in the video.

**Describe the solution you'd like**
A progress bar that shows the total length of the video and time remaining in the video. That way we can give a count-in to those that need to know how much time is remaining in the video and when the video is about to end.

**Describe alternatives you've considered**
In the past I have used OBS Studio to play videos which shows this exact information making it easy to give hand signals and count down the last 5 seconds to hand back to the emcee.
