Provide option for saving box coordinates in Pascal-VOC format. (#13272)

* Provide option for saaving box coordinates in Pascal-VOC format.
- Added save-format argument for saving box coordinates in Pascal-VOC format (Xmin, Ymin, Xmax, Ymax) when save_txt is True, 0 for YOLO and 1 for Pascal-VOC, By default - 0

* Auto-format by https://ultralytics.com/actions
