Bug Description

I noticed the StarmapParallelization class has been moved to pymoo.parallelization in the last version, therefore causing an ImportError. It's not a big problem, but also not something expected for a version change from 0.6.1.5 to 0.6.1.6.
Just wanted to let you know in case you were not aware.

Minimal Code to Reproduce

from pymoo.core.problem import StarmapParallelization

Error Message

PyMoo & Python Version

pymoo 0.6.1.6, Python 3.12.10
