Add data from Treibhausgasbilanz Ebersberg

The Landkreis Ebersberg biyearly publishes a greenhouse gas balance:

• 2016: https://www.energieagentur-ebe-m.de/data/dokumente/konzepte%20ebe%20m/2020_05_12_Treibhausgasbericht_Landkreis_Ebersberg_2016_komprimiert.pdf
• 2018: https://www.energieagentur-ebe-m.de/data/dokumente/konzepte%20ebe%20m/2020-12-18_Treibhausgasbericht_Landkreis_Ebersberg_2018_web.pdf
• 2020: https://www.energieagentur-ebe-m.de/data/dokumente/sonstige/2022_11_22_THG_Bilanzierung_final_Web.pdf
• 2022: https://www.energieagentur-ebe-m.de/data/dokumente/thg_bericht/THG_Bilanzierung_final_Web.pdf

The report also includes data aggregated by municipality, so we do also have numbers specifically for Vaterstetten.

As of March 2021, it was not intended to publish the data in a machine-readable format, but it could be worth asking if this would be possible for the 2020 report (published in 2022).

The data also includes the number of electric vehicles by municipality, which is not possible using the public data by the Kraftfahrtbundesamt (see #37). Maybe they get the data directly from the Kfz-Zulassungsbehörde in Ebersberg.
