Empowering X-AnyLabeling with YOLOv9 Model Support

[CVHub520]

Hey @WongKinYiu, big thanks for your outstanding work!

I've seamlessly integrated yolov9 into X-AnyLabeling, marking a substantial leap in our capabilities. YOLOv9 proves to be a game-changer, offering robust object detection trained on an extensive dataset of labeled and unlabeled images. This integration elevates X-AnyLabeling, providing a more comprehensive and industrial-grade solution for image data engineering.

This is not an issue but a celebration of a successful integration. Once again, thank you for your exceptional contribution. Excited for more successful collaborations ahead!
