Add RSS support for emergency alerts

In Germany it is possible to get emergency alerts over RSS (example: https://warnung.bund.de/api31/mowas/rss/091620000000.rss). Would it be possible to add this feature to the emergency alerts options beside CAP and US national weather service? If you want to add just a German emergency alert option, you could use the above link and provide and option to choose the cities (more than one) from were it should get the emergency alerts from. A list of all cities with there codes could be found here: https://www.xrepository.de/api/xrepository/urn:de:bund:destatis:bevoelkerungsstatistik:schluessel:rs_2021-07-31/download/Regionalschl_ssel_2021-07-31.json Because emergency alerts are area based (State), you must always ignore the last 7 digits from the city code and replace it with zeros (0), like in the example provided above.
