Minor import issue of vlm_tools

[yuezhezhang]

Hi,

Thanks for the impressive work! I am trying to run the vlm-tamp and meet some minor import issues in

• line 12 of vlm_api.py
• line 12 of vlm_utils.py

If I may understand correctly and update them to:

• from pybullet_tools.utils import wait_for_user
• from pybullet_tools.utils import get_link_pose

They should work.
