Bietigheim-Bissingen: realtime_free_capacity is -12

[AbdullahiFatola]

We discovered that the realtime_free_capacity for the park data of Bietigheim-Bissingen has -12, which should not be. After checking the raw data that we recieved from the city, it happened that the capacity is 67 and realtime_capacity is 79. realtime_free_capacity seems to be calculated with these 2 values in the converter.

Few months ago, we amended the park-api-v3 to set same value for capacity and realtime_capacity in such case, when realtime_capacity is greater than capacity. Could we also set the realtime_free_capacity in this case as 0 to avoid negative values?

Back then, you added a check like this here: https://github.com/ParkenDD/park-api-v3/blob/main/webapp/services/import_service/generic/generic_parking_site_import_service.py#L199 .

In order to test it, I would recommend to write a test for this, to make sure that all different situations are covered. Like this: https://github.com/ParkenDD/park-api-v3/blob/main/tests/integration/services/import_service/generic/generic_import_service_test.py
