Building upon the dwdbulk codebase

[amotl]

@jlewis91 maintains a well done implementation at [1]. While it is somehow derived from this project, it is based on modern Python (Python 3.7+ & Pandas). Thanks for this, @jlewis91!

It currently seems to implement acquisition of "observation" data [2] of

• precipitation for the 1_minute resolution
• air_temperature, precipitation, solar, wind, extreme_temperature and extreme_wind for the 10_minutes resolution

as well as acquisition of "forecast" data.

It would be cool to join both projects again in any way. The best thing would be to build upon @jlewis91's efforts and add back improved versions of a CLI interface and a caching layer. SQLite support should be dropped altogether.

In order to conveniently acquire forecast information from DWD, I've created https://github.com/earthobservations/wetterdienst/issues/70 and will deliberately close this issue in order to divert further discussions to Wetterdienst, the successor library of dwdweather2.

@jlewis91, @gutzbenj, @wetterfrosch et moi recently discussed the future of Wetterdienst within https://github.com/earthobservations/wetterdienst/issues/50.
