new-logic 2/X: Typesafe settings

[robojumper]

• Removes the Settings class to separate data fetching from actual options/settings concerns
• Bases Settings type on options command rather than human readable name
  • Avoids breakage when settings get renamed
  • More closely matches ssrando-internals
  • Works better with IDEs hints, autocompletion
• Automatically generates a type checked Settings interface based on upstream data, which is extended with preliminary support for future features
• Drops support for pre-2.0 settings
