Integrate feedback from code review (#300)

- Sort dependencies alphabetically
- Rename classes and flux commands for consistency with others
- Use backticks for options and their defaults in `@Description`
- Remove unused code, add final modifiers

See https://gitlab.com/oersi/oersi-etl/-/issues/238
