IOS client fails to load playlists due to response missing expected fields

[zlalvani]

Basic Troubleshooting

• I have checked for similar issues, and my issue is not a duplicate. (Check closed issues as well)
• I have checked for pull requests that may already address my issue.
• I am using (and my issue is reproducible on) the latest version of youtube-source.
• My issue is reproducible with IPv6 rotation.
• I have confirmed that my issue is reproducible with the minimum viable clients (MUSIC, WEB and TVHTML5EMBEDDED)

Version of youtube-source

1.8.3

The search query/queries, URL(s), playlist ID(s)/URL(s) or video ID(s)/URL(s) that triggered the issue

https://www.youtube.com/playlist?list=PL9C4858832F52F993

The JSON response is very large (over 1MB) but I've attached it. Essentially, the response does not match the assumptions made here - there is no field content.playlistHeaderRender and the structure deviates even more later. While the exception occurred before it was called, I noticed that extractPlaylistVideoList will also fail as the structure of the response also deviates there.

ios-playlist.json

What is your client configuration?

MUSIC, IOS, TVHTML5EMBEDDED

The README implies that IOS should support playlists so in the short term it might be best to update it to reflect the lack of support
