Move to new PEP 517 standard with poetry and more "meta" package updates

[Nachtalb]

This pull request migrates the project from using setuptools to Poetry, in line with PEP 517, to improve the project's overall development experience and maintainability. The key enhancements include:

• Streamlined dependency management, ensuring consistent and deterministic builds across environments.
• Simplified package publishing, reducing the complexity of deployment.
• Seamless integration with virtual environments, improving isolation and consistency.

With this migration, the project benefits from a more robust build process, ultimately contributing to higher code quality and a smoother development workflow.

In addition to poetry, I have also updated the remaining "meta" packages (mypy, black, pre-commit etc.):

• Upgraded pre-commit modules to their latest versions, ensuring adherence to current best practices and coding standards.
• Performed an update of all code files to ensure they pass the newly configured pre-commit checks, enhancing overall code quality and consistency.
• Replaced Flake with Ruff, a modern and extensible linting tool, for more accurate and configurable code analysis. This switch allows us to maintain a high level of code quality while also tailoring the linter to our project's specific needs.

Anyway, checks are passed, also i've tested building project environment with Python 3.7.16 and 3.10.11, everything went well.
