Determining whether a stream is live

[planetarian]

One problem I had today was that I needed to be able to distinguish between finished/live/upcoming streams within a channel playlist, to determine whether a channel's streaming "status" has changed so I can then decide whether to pull further information about the videos in question using the official API. Finished streams/videos was simple because they just have a duration that isn't 00:00:00. Live/upcoming streams were impossible to distinguish from each other, though, because they both had the same zeroed duration and no other distinguishing features.

I found a solution for this, which is to check _content->badges->metadataBadgeRenderer[0]->style for the value BADGE_STYLE_TYPE_LIVE_NOW. I don't know whether it's up to the project's code standards, but I implemented it in my own fork of and it's been working reliably so far.

Since this project is in maintenance mode and not accepting new issues/PRs, I'm just posting it here. The commit with the relevant changes is here:
