Native playlist downloading

[ckp95]

Hey, saw this in Hackernews, looks pretty neat.

Even though the README only mentions channels, I know that yt-dlp also supports downloading playlists. When I give it a playlist that has videos that were deleted, yark breaks. This is common in music playlists, for example this one.

I had a quick look in the code, I managed to get it to work with this simple hotfix:

diff --git a/yark/channel.py b/yark/channel.py
index 4863823..26eb7af 100644
--- a/yark/channel.py

I'm not making a formal PR because you might know of a cleaner way of implementing this check, but you're welcome to apply this patch if you want. Also it might be good to mention in the README that it works on playlists too, not just channels.

Thanks for the input, i'll take a look at it tomorrow. Playlist viewing (#27) is in the upcoming v1.3 so it'll complement this kind of download nicely. There needs to be a seperate intake stream for playlists as new because yark is geared for channels right now

just leaving a +1 for playlist downloading - just to motivate it - i'd like to back up every video i've ever "liked" as a simple way of guarding against bitrot and enabling proper search since youtube search sucks.

thank you for this project @Owez and looking forward to v1.3!
