Reorganized copy of angkul07/ego-data, split into per-object folders.
What changed
Source is a flat set of numbered N.mp4 + N.hdf5 pairs.
All episodes are the same task (basic_pick_place, type reset); only the manipulated object varies.
Episodes are grouped into one folder per object, parsed from each hdf5 object attribute (color/shape stripped). Original numeric IDs preserved.
