Add RadioBrowser to the radios

[d-faure]

https://www.radio-browser.info/

This is a community driven effort (like wikipedia) with the aim of collecting as many internet radio and TV stations as possible. Any help is appreciated!

• Free for ALL!
• Data license: public domain, software license: GPL, server software: open source
• Open API for usage in own apps
• Everyone is free to use the collected data (station names, tags, links to stream, links to homepages, language, country, state) in their works. I give all the rights I have at the accumulated data to the public domain.

And it has an API: https://api.radio-browser.info/
