Revamp the settings system (#7)

- A Settings Provider system to utilize addressables for loading settings at runtime
- An editor UI for easy modifications of the settings objects
- A split out developer settings functionality to keep gameplay and nitty-gritty details separately
- Most settings migrated out of game objects and into the new system
- An additional Editor utility for fetching the settings at editor runtime, for gizmos, visualization etc
