Missing dependency - ModuleNotFoundError: No module named 'packaging'

[commonism]

When after installing bitwardentools in an empty 3.12 venv

>>> import bitwardentools
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/tmp/demo/lib/python3.12/site-packages/bitwardentools/__init__.py", line 1, in <module>
    from bitwardentools.client import *  # noqa
    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/tmp/demo/lib/python3.12/site-packages/bitwardentools/client.py", line 24, in <module>
    from packaging import version as _version
ModuleNotFoundError: No module named 'packaging'

installing packaging from pip helped.
