Convert Genetic Algorithm code into C++

[Pocwiardo]

Code from GA_in_Python branch should be converted to C++ in order to be used with JUCE Plugin framework.

I started the job on GA_in_Cpp and converted the core functions. The only remainings are mutation function (it only has some mutations) and fitness function (only two scores are calculated). Conversion is not good for now, used chatGPT, but it works after my corrections.

Fitness and mutation added. I still need to do some modifications regarding music theory, but it can wait. Now the thing to do is to optimize and repair bugs:

• sometimes, somewhere there are functions that go out of vector bounds,
• algorithm converges to solutions with MIDI values under 12 for some reason. There must be some fragment of fitness function that promotes that. We usually perform operations on MIDI values mod 12, but values themselves should be somewhere in the middle of 0-127 range
