Better / additional data source

[Bouni]

As the tsv files from impfdashboard does not show the percentage of booster shots I searched for a data source and stumbled over this here, also by RKI:

• https://github.com/robert-koch-institut/COVID-19-Impfungen_in_Deutschland/blob/master/Aktuell_Deutschland_Bundeslaender_COVID-19-Impfungen.csv
• https://github.com/robert-koch-institut/COVID-19-Impfungen_in_Deutschland/blob/master/Aktuell_Deutschland_Impfquoten_COVID-19.csv
• https://github.com/robert-koch-institut/COVID-19-Impfungen_in_Deutschland/blob/master/Aktuell_Deutschland_Landkreise_COVID-19-Impfungen.csv

There are even datasets down to the district level, would be awesome to have those available as well 😄

Hi, I can look into it when I find some time. Otherwise you can of course create a PR again if you want 😉
