the meaning of eef_sim_pose_state

[haofuly]

Hi, thanks for the valuable dataset contribution.

I use the Agilex_Cobot_Magic_close_drawer_bottom dataset as an example.

dataset = LeRobotDataset(repo_id="Agilex_Cobot_Magic_close_drawer_bottom")
item = dataset[200]

print(item['eef_sim_pose_state'])
# tensor([ 0.2329,  0.2941,  1.0534,  2.0357, -0.0219,  1.5082,  0.5111, -0.0441, 0.8445,  1.9425, -0.0792,  1.9126])

print(item['observation.state'][7:10])  # corresponding to left_eef_pos_x_m and y and z
# tensor([-0.0059, -0.0073,  0.2785])

Why the eef_sim_pose_state is different from the left_eef_pose_x_m? Is it because that the definitions of the base of coordination system are diverse, as you mention in readme?
