Bounding box query APIs slowed down by join operations #1177

The edits in src/spatialdata_plot/pl/utils.py from this PR https://github.com/scverse/spatialdata-plot/pull/765/changes highlight an opportunity to improve performance in the bounding box query APIs.

I suggest to check this only after we are done with the coordinate transformation refactoring, since after that the code in spatial_query.py will become much easier to read.
