[feature] quality change support

[nazar-41]

Hello @ChrisMash . I have an HLS master file that contains 4 quality types. I would like to switch between qualities smoothly while video is playing. Here how my hls file looks like (https://bv-storage.belet.me/videos/UCEkd3Rj_MSv8v6aA0h1G4fg/KEInn8yLDqM/master.m3u8)

I'm afraid it's been too many years since I was working on AVPlayer APIs to remember much about this so I'm not really sure what the options are. Off the top of my head I would have thought maybe the different quality levels would be accessible as different tracks, but from the sound of that other repo you linked it's not something Apple actually expose APIs for, hence why they've gone down a local proxy route, which isn't something I've done before myself and can get a bit complicated I think, so I can't really help you out on this I'm afraid!
