import jupyros is failing

[jlmeunier]

Hi there!

Several names are unknown in the code.
It started by Unicode in file jupyros/ros3d.py
=> I explicitly import it by a from traitlets import Unicode
But then, I'm getting a:

>>> import jupyros
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/meunier/miniforge3/envs/ros_env2/lib/python3.9/site-packages/jupyros/__init__.py", line 16, in <module>
    from .ros3d import *
  File "/home/meunier/miniforge3/envs/ros_env2/lib/python3.9/site-packages/jupyros/ros3d.py", line 78, in <module>
    class TFClient(widgets.Widget):
  File "/home/meunier/miniforge3/envs/ros_env2/lib/python3.9/site-packages/jupyros/ros3d.py", line 95, in TFClient
    ros = Instance(ROSConnection).tag(**sync_widget)
NameError: name 'Instance' is not defined

I've done the standard installation of Robotstack, for ROS Noetic, followed by: mamba install jupyter-ros -c robostack
On a x86_64 macchine running Ubuntu 20.04.6 LTS
