Setup

This release does not has any content, but contains the basic project setup:

• empty pie_utils package in the src folder
• empty tests package
• setup.py - this project is ready to install
• .pre-commit-config.yaml - definition of code quality checks
• README.md - simple setup instructions
• GitHub workflows: code-quality-main.yaml, code-quality-pr.yaml, and test.yaml
• and: pyproject.toml, .gitignore, and LICENSE

Note: CI is red because there are not tests to run.
