Temp workaround for Cuid loading issue

[vbrodsky]

Description

Original code used Cuid type defined libs/labelbox/src/labelbox/data/annotation_types/types.py. While this had no problem for integration tests on staging, production integration tests failed, for example see https://github.com/Labelbox/labelbox-python/actions/runs/10152094005/job/28072753651

The error is because numpy was required (?) but not loaded.
Production is a different github action and different code. However I am not sure whether the problem is with the github action or with our code that requires numpy which should be an optional package? Out of abundance of caution and due to other project commitments, I have made this fix.

I will make a separate story to investigate further
