Channels: Add sort options to streams

[src-tinkerer]

Uses the same method that is used for videos. We create continuation based on the sort option. One note though, produce_channel_livestreams_continuation and produce_channel_videos_continuation are almost identical, so is it better to simply make a singular function that produces the continuation based on the content?

[SamantazFox]

Yes, merging the two in a single function is strongly preferred.
Also, please remove produce_channel_livestream_url. It has no use (the function you copied, produce_channel_videos_url was only used to bypass captchas back then and will be discarded one day).

[src-tinkerer]

I made the requested changes but couldn't test it yet because YouTube is blocked in my country, shouldn't be merged until then.

Code looks good! I'm only asking for a few style/syntax changes ^^

[src-tinkerer]

Done, sorry for delay. Been busy with midterms.

[SamantazFox]

@src-tinkerer yeah, sure, no problem ^^ With my 60+ pending PRs to review, that'd be quite ironic for me to ask you to reply in a timely manner x)

[src-tinkerer]

Will test this week

Okay done testing and live stream sort works.
