Adopting-ish openZIM bootstrap

[rgaudin]

Getting closer to openZIM bootsrap (we build via setuptools for Cython extension)

Fixes #195

• Upgraded build and dev dependencies
• Removed setup.cfg (moved metadata to pyproject.toml)
• Replaced isort and flake8 with bootstrap's ruff
• Added config for pyright (disabled for now as libzim has no type hints)
• bootstrap conf for lint/check/test
• updated linting to match

This will be followed by a PR with type stubs
