RuntimeError: Error building extension 'fast_cocoeval'

Start by reproducing the Windows import failure through yolox/layers/init.py, which loads yolox/layers/fast_coco_eval_api.py and jit_ops.py. Inspect the PyTorch extension build output and verify that the fast_cocoeval extension can be built and imported successfully; no specific test is named in the issue.
