Project renovation

[augustjune]

This project embeds interesting ideas and may have value for other people. Because it was originally designed as a generalization over different implementations of genetic algorithms for different problems and not as an open-source library, it is even remotely ready for the user.
This issue should address major improvements that should be done in order to make the project appealing for interested users.

List of the changes to be made:

• Replace Akka streams with FS2
• Get rid of Scala parallel collections
• Generalize over the effect of fitness function evaluation (should long-running computation be considered as an effect?)
• Improve benchmarking
• Setup CI and release process
• Improve docs including README file
