Updated with some fixes for light mode and size of title for longer state names.

New version with

• automatic location detection
• and configurable widget parameter to set the state or Germany
• visual improvements

Big thanks to @mkreuz.

@mkreuz we should look into caching the location, so it only runs on updates when the device is unlocked and not in the background, since location data is not available and resulting in an error.

@n0rdlicht Good idea. I implemented a FileManager to store the last location. If no location is available, the cache is read otherwise it is updated with the current location

Updated from the fork.

Updated to refelect changes to RKI dataset. Now showing initial round of vaccinations for daily delta and vaccination rate.
