Berlin: Check market coordinates with bounding box #619

Context

A couple of times market locations in Berlin had wrong coordinates assigned. This could be seen by manually looking at the distribution of markets on the map.

Proposal

The preprocessing script checks up front if all coordinates are within a defined bounding box. Hence a bounding box for Berlin must be defined. It might not exactly match the boundaries of the state. If outliers are detected the script can output them so they can be reported to the data publisher immediately.
