Refactor and simplify framework

[gmontamat]

Please note there's a major overhaul of this package taking place:

• Copy structure of https://github.com/microsoft/python-package-template
• Adapt to python3.10+ (f-strings, linting, type hinting)
• Get rid of duality individual-model (simplify classes)
• Rewrite XGBoost
• Rewrite Genetic CNN model
• Add a scikit-learn model
• Simplify dataset retrieval for mnist, iris, fashion-mnist, and others
• Use redis instead of rabbitmq for distributed algorithm
• Fix second generation bug in client (Connection failure on second generation #18)
• Use proper logging instead of prints
• Add module section with predefined parameters
• Automate CICD workflows (linting, testing, and publishing) with GitHub Actions
• Create CONTRIBUTE.md
• Add an index to the README
• Add repo badges
• Implement Genetic CNN or other in PyTorch
• Add public/private key validation for clients

edit: the core parts of this refactor is complete. I'm leaving python-packaging related bullet points to another PR.
