Library problems

[TomiMilosic]

Hi @lukapecnik! It seems NiaPy has been updated so "from niapy.algorithms.utility import AlgorithmUtility" (optimization_widget.py) won't work anymore. Please fix it as soon as possible ;)

I pasted two pictures for you to easier to solve the problem.

best regards!

@TomiMilosic, could you help us in solving this issue? This task should not be too difficult. You just need to replace current niapy interface with the newest version.
