[youtube] Return to old feed extraction code as it *seems* like that 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
