Investigate how packages are built/created

[John15321]

Part of https://github.com/John15321/rust-pip/issues/1 task.

• Investigate all possible project setups that can be used in Python projects (setup.py, pyproject.toml etc.)
• What tools are needed to build/create a Python package?
• How does creating a package look like?
• How does a Python package look like inside when it's already created/or what types of packages are there (so like wheel etc)?
• How are dependencies resolved?
