You finally can record sub-only streams and streams without ads if you are a subscriber. Read description to self.oauth_tok_private.
Moved from Kraken API to Helix due to Kraken isn't available anymore.
Rerun detection removed - Helix doesn't have it.
Little fix to ffmpeg args.
Added --hls-live-restart to streamlink subprocess. This allows you to increase the refresh time without losing the start of the stream.
