Add support for Light Strip, name changes, Idenfity and Settings

[frenck]

Proposed Changes

Quite a larger update of this library.

• Since we support multiple "Light" devices now (and not just the Elgato Key Light), all occurrences of "Key Light" have been replaced by "Light".
• Added support for the Elgato Light Strip
  • This adds support for colors
  • Allow using the Light Strip with temperature values as well
• Updated all sub dependencies
• Added ways to read device settings (which can be used to figure out if the device supports color)
• Added method to blink an Elgato light: Identify
• Added additional validation to the light calls for invalid data
• Kept test coverage at 100%
