Fix maximum version for Python and make all tests pass

ziotom78 · ziotom78 · commit 5a35e6d068cb · 2026-04-13T14:04:21.000+02:00
The test in test_scan_map.py, `test_scan_map_no_interpolation`, was
simplified a lot: the first part re-implemented the code of the binner
but was no longer working because of updates in AstroPy pointing
precision.
