First, ensure that we calculate the bbox of the imported elements.
If the total BBOX is outside our allowed value, refused to import. This
needs to be scaled or addressed in an external editor
If the bbox fits, then make sure that we clamp it such that the largest
element is still within our bounds
Fixes https://gitlab.com/kicad/code/kicad/-/issues/18523
Removed no-longer-required differentiation between importing
footprint vs board objects.
Renamed files to match the dialog.
Made Position At and Set Layer optional checkboxes.
Removed Group Items checkbox. (In the unlikely event that you don't
want a group, do an UnGroup after importing.)
Flattened out labelled-sizers in the dialog.
Removed importers blacklist, which hasn't been active for at least 4
years.
Fixed undo/redo bug that caused items to be no-longer-grouped after
a redo.
