[Feature Request] Browse while playing

[gusals3587]

Basically, I want to look at the comments while watching video, I came up with a very hacky way (aka POC) of making the mpv subprocess entirely separate, then pointing all the stdout to devnull, but since I don't really know much about the codebase of mps-youtube, I'm pretty sure I broke like a half dozen edge cases and deprecated a couple of functions. Oh, and it only works with mpv, I need to find somebody who can turn this into a useful / more versatile feature

Issue / Suggestion

I've implemented the POC (proof of concept) on #982
Some things to point out are

1. I've edited the player.py so it doesn't terminate the player, that means deleting the next, previous, etc
2. I've also edited the player.py so mps youtube itself doesn't output anything, which means deleting the _playback_progress
3. In mpv.py I've switched stdout to subprocess.DEVNULL for detaching the mpv output prompt from terminal
4. Also in mpv.py, I've changed the stderr to subprocess.DEVNULL as well since I think that it's more sensible (please correct me if there's any reason why you opened the file)
5. I've added ' &' to cmd so it detaches completely from it's parent

This is actually very hard to do right with the current state of mpsyt. I tried this once a while back and failed. It's better to refractor the core to be modular before attempting things like this.

The above is the commit for my attempt. It was a very beginner-to-python-me who coded that, so it might be possible I could do better today. I'm not sure about the state of that branch. It might work, it might not.
