129 add bayesian optimization

[jkriwet]

Closes #129

[FWuellhorst]

@jkriwet Thanks for the feature!
Can you further:

• include the option in the example for optimization?
• Increase the version number to 0.5.0 due to the new feature? Also add the changelog.

@jkriwet : When doing the review, can you add the following kwarg?

"""gp = None"""
gp = kwargs.get("gp", None)
if gp is not None:
    optimizer._gp = gp

Done. Also changed example as discussed internally

Why different version then in requirements?

[jkriwet]

Changed to version in the requirements. 1.5.1 works, but not for python version <= 3.9 (or 3.8). Since nothing important is changed in 1.5.1, fixing to 1.4.3 for now

@jkriwet : Looks really nice the new feature and example! I further added markers to see which point is where.
pymoo seems to have resolved the issue in their latest version, but removed all factories to avoid development efforts for them. This would mean we have to maintain a dict for string-class relation of pymoo objects, which I would not do to avoid overhead.
If the new pymoo version is of interest, we could remove the option to pass a string and just have users import the class beforehand.

@FWuellhorst Thank you! Since the cma imports seemed to still make problems i have now changed the algorithmn imports and pulled them from pymoo to ebcpy.

In pymoo, when choosing the algorithm over the get_algorithms() function, all algorithms are imported. Only the CMAES algorithm makes problems with the cma import. I have deleted that as an import (and algorithm choice) for ebcpy and now everything works, also in the CI for python >= 3.10.

I do think the string-class relation is way more convenient and therefore dont see any reason as of yet to chang to the new pymoo version.
