NotUniqueError not available for some versions of bayes_opt.util

[holm10]

Users have reported NotUniqueError not being available for some bayesian-optimization versions above 2.0.4:

ImportError: cannot import name 'NotUniqueError' from 'bayes_opt.util'

To recreate:

pip install bayesian-optimization==3.0.0
python

1 from bayes_opt.util import NotUniqueError

ImportError: cannot import name 'NotUniqueError' from 'bayes_opt.util' (/lib/python3.11/site-packages/bayes_opt/util.py)

@yichenfu the install could be modified to limit the bayesian-optimization to v2.0.4, but that will limit the flexibility if people want to use higher versions for other projects. Not sure how big of a difference between v2.0.4 and v3.0.1. Probably figuring out a solution that works for both versions would be the best.

@holm10 I will take a look and get back to you soon!
