Request to add DEIM object detector

### Model description DEIM is a SOTA real-time object detector based on DETR architecture and even beat the recent D-FINE on checkpoints that were not pretrained on object365. DEIM accelerates the convergence by improving the quantity and quality of matching with Dense O2O (one to-one) and MAL (Matchability-Aware Loss) respectively. It can be used to improve existing object detectors. ### Open source status - [x] The model implementation is available - [x] The model weights are available ### Provide useful links for the implementation Paper : https://arxiv.org/abs/2412.04234 Code : https://github.com/ShihuaHuang95/DEIM
