should fix feeds as well.

This moves feed extraction from using html content to json metadata. However, loading additional pages no longer works.

The _extract_video_info function also returns a continuation object that contains some metadata that - together with an API key that is in the page source - might be used to request the next page.
If an object looks like a video (it has a `videoId` key), assume that it is.
…change was reverted

The old code now works again, but it downloads without limit. This is why a limit of 1000 videos is added, it can be overwritten with the `--max-downloads` option - that way, only so many ids will be extracted as videos downloaded
In order to extract videos from further pages, we need to get various variables that are in an argument to the `ytcfg.set` call in a script on the feed page.
If the markup of the page changes in the future, it might be possible that _FEED_DATA still works, but the other regex does not. SInce it is not necessary for the first page of videos, we make sure the program doesn't exit before extracting them.

TL;DR: Extract the first video page even if there are problems
Seems like this attribute is moved every few weeks, so we just extract both and use the one that is present.
This now supports declarations like `window["ytInitialData"] = ...` and `var ytInitialData = ...`
