Crossing QA: Filter data on landuse=residential / Input multipolygon

(This is low prio IMO and likely out of scope. But wanted to document the idea…)

When doing the QA for a larger region, we want to get an idea on the total number of intersections to validate. In this case, the non-residential intersections are likely out of scope for the project.

So maybe we could have a filter that shows only junctions that are within the buffered `landuse=residential` areas? ([Example](https://www.openstreetmap.org/way/122432927/history#map=16/52.73558/13.23360))

Or, maybe it would be better to be able to upload an area of interest multipolygon which the app transforms in the overpass bbox and then filters the QA responses on?
