Implement YOLOv10-inspired loss function

[clementpoiret]

Implement the loss_fn in hackathon/objectdetection.py. This includes calculating classification, bounding box regression, and objectness losses, and combining them, based on YOLOv10 principles.

With a solid foundation in deep learning and experience in implementing loss functions, I will develop the loss_fn in hackathon/objectdetection.py according to YOLOv10 principles.

This involves calculating and combining classification, bounding box regression, and objectness losses to optimize object detection performance."
