YouTube: Allow fetching more than 50 items

[madiele]

Hi i've got an issue on my repo about raising the item limit from 50 (the limit for a single YouTube API call)

madiele/vod2pod-rss#90

I've given a look at the code and it seems there is already some kinda of logic for it but it was manually disabled with this line response = {'nextPageToken': ''} before the loop for both channels and playlist

I guess maybe to prevent fetching 3000+ videos accidentally on big channels, do you thing is possible to re-implement the feature back-in some way?

If you want I can open a PR myself too, just tell me what is your preferred solution and I'll code something as soon as I have a spare weekend✌️

Admittedly, my understanding of the Youtube code is lacking since it was written by @aquacash5, though after doing some poking around with this I believe that the code pulls the first 50 results, then if those results include a 'nextPageToken' key, it pulls the next page:

I've created a branch (https://github.com/amckee/PodTube/tree/Issue20) that includes extra logging in this regard, reporting the number of items and pages that a channel request results in:

2023-08-11 18:23:01,271 [INFO] Got 52 videos from 3 pages

You might have some luck with this alternate API https://developers.google.com/youtube/v3/docs/channels/list. I haven't tested it, but it looks like it could be a drop-in replacement.
