Keeping addresses of RSS feeds up-to-date

[matthiasroos]

Thanks for this great package and for the big collection of RSS feeds for so many news sites.

But how and when did you collect the addresses? The two sites from Germany I tried both had problems: one linked to a broken website (the catching did not work at all), the other one is not the feed you want (some outdated podcast feed). Perhaps it is a good idea to have native speakers review the corresponding feeds, I would volunteer for the german ones

The correct addresses are:

• sueddeutsche.de: https://rss.sueddeutsche.de/app/service/rss/alles/index.rss?output=rss
• heute.de: https://www.zdf.de/rss/zdf/nachrichten

This leads to a second issue: Using a sqlite database might be convenient, but is not so practical to be tracked in git, as mentioned in another Issue. Therefore, I could not contribute with a Pull Request.
