Set up Table for Keepright
Current implementation for keepright: request keepright errors for each buffered osm object, upload them into a separate table in the database, and calculate the number of errors per object.
Alternatively, a dump file of all errors can be downloaded and set up as a table in the db: https://www.keepright.at/interfacing.php#DUMP. This way, the keepright table only needs to be queried with the bboxes of the osm objects to count the number of errors per object.
This approach is possibly faster than the current implementation but would need an update mechanism for new queries.
