* Fix detect.py URL inference

Allows detect.py to run inference on remote URL sources, i.e.:

```python
!python detect.py --weights yolov5s.pt --source https://ultralytics.com/assets/zidane.jpg  # image URL
!python detect.py --weights yolov5s.pt --source https://ultralytics.com/assets/decelera_landscape.mov  # video URL
```

* [pre-commit.ci] auto fixes from pre-commit.com hooks
