Why is use_lidar set true for detr3d

[shubham-gupta-iitr]

Hi, Thanks for this amazing work. I was going through the code and saw that you've kept use_lidar=true here for DETR3D https://github.com/WangYueFt/detr3d/blob/main/projects/configs/detr3d/detr3d_res101_gridmask.py#L23 I was expecting since its an image-based method, it should be kept false, and also the file should look similar to- https://github.com/open-mmlab/mmdetection3d/blob/master/configs/_base_/datasets/nus-mono3d.py

Thanks

Sorry that was a typo and shouldn't affect the results. I've just fixed it.
