[Feature]: Run ruff formatter on codebase

Is your feature request related to a problem?

Code quality improvements.

Describe the solution you'd like

Run ruff formatter on all *.py files. Also should set the target Python version for the code repository in pyproject.toml (e.g. 3.10?) so when various code checking and formatting tools run they know what syntax is valid.

Describe alternatives you've considered

Ruff is starting to replace usage of the long-standing black8 and brunette formatters.

Additional context

Recommend adding .pre-commit-config.yaml in project root with the following once ruff has been run, so those that use pre-commit will ensure that new code automatically is formatted to the project's standards as well.
