Method for converting dataset to .pkl files

[YJF6666]

Is there any code to convert .pkl files, similar to this one: https://github.com/open-mmlab/mmdetection3d/blob/1.0/docs/en/datasets/nuscenes_det.md

Maybe you can change nuscenes_converter.py from BEVFormer to convert pkl files, but it is difficult. I tried, and successfullt get the pkl. You may change the class_name, reference cooridinate, num_cam and so on.
