Restructured codebase to be more flexible

[robere2]

• Allows LEDs with any number of individual LEDs within them instead of just 3 colors.
  • E.g. instead of RGB LEDs, you can have single-color LEDs, or sets of LEDs to create shapes.
• Allows more complex animations being passed to LEDs, as opposed to just a blinking animation.
