Extract Ego2Global attribute from the dataset  #120

Hi author, I am researching on how to incorporate information between consecutive frames in OpenLane-v2 dataset. In Nuscenes, the SDK provides API to extract Ego2Global_translation and Ego2Global_rotation from the dataset (nutonomy/nuscenes-devkit#487). How can I extract the same information from OpenlaneV2. I went through the code of the API and could not see the relevant stuff.
