Fixes #6929
@yoohot please have a look at the pull request changes and report back if this fixes the issue by testing a couple of streams. The live streams I've tested so far all seemed to be working, but I want to be sure.
https://github.com/streamlink/streamlink/blob/master/CONTRIBUTING.md#pull-request-feedback
The retured data from their website unfortunately doesn't include bitrate information anymore, so the currently available qualities ("full_hd1" (best), "hd1", "sd2" and "sd1" (worst)) need to be hardcoded with custom weights. I don't know if there are streams with different quality names that are missing in the current version of this PR.
HLS streams were not working, so I kept the HTTP streams.

This is the quality data, but none of this maps to the given quality names:
