CARLA overhead object detection test data

[swsuggs]

@jprokos26 could you double check that you can get the new dataset when you run a config? This version has two splits "test_hallucination" and "test_disappearance" so just set the config accordingly:

"dataset": {
        . . .
        "eval_split": "test_hallucination",
        "name": "carla_over_obj_det_test"
        . . .

I will add baseline results to PR #1959

Tested working with both splits

test_disappearance
