Integrate `isort`

Ready for CR 🕺🏼

Goal

Arrange Fuse's code base, and particular the imports in each file. For more info see isort.

Key files:

• pyproject.toml - config isort to be compatible with black
• .pre-commit-config.yaml - add isort as a pre-commit hook
• /.github/workflows/lint.yaml - Added isort into github actions

Outdated. Will be easy to create a new one from scratch
