"Import a KSP .mu model as a Prop" doesnt seem to work

[StoneBlue]

Per our Discord discussion on 07/04/22 @ UTC 14:59, pressing the button & selecting a .cfg, throws errs for \prop\operators.py.... I made the suggested change to line 44 (import_prop to import_prop_op), but then I get two TypeError(s) on that variable, that its missing 2 required positional arguments: 'context` and 'filepath'
