some utils for vcoco-dataset , help to make a new dataset like vcoco using lableme

• trains_json.py: convert the JSON file annotated by Labelme to the GROUD TRUTH file of TEST_VCOCO ,which is called new_dataset_test.json
• new_vcoco_eval.py: rewrite the official vcoco_eval file of vcoco, mainly changed the test_vcoco file to read directly into our own test_vcoco generated by trains_json.py,which is called new_dataset_test.json
• test.py: the file for test, output mAP
• 1.json,2.json……： the labed file generated by Labelme
• 111.json: generated by your HOI model in your own dataset
