InternData-A1 dataset taken from InternRobotics/InternData-A1,
with the tarballs extracted and directory structure "transposed" so that the top-level subdirectories are the four embodiments.
For the franka embodiment, there are two different feature spaces, so we split it into the franka-1 and franka-2 directories.
The feature spaces differ in image shape and gripper value range.
