Customize LED config by registry settings

[JohnAZoidberg]

Solves #3

TODO:

• Currently reconfiguring requires uninstalling the device and driver, then creating the registry entries and re-installing the driver. It should work just by disabling/enabling the device. Disabling device should work #5
• Should create a tool to dump the LED array configuration so that we can check if the lamp positions are correctly calculated

Tested arrangements:

• 0: Circular, layers of 8 (e.g. when 16 LEDs in total, two layers of 8 LEDs)
  • Works with 4 LEDs
  • Works with 8 LEDs
  • Works with 16 LEDs
• 1: Circular, single layer
  • Works with 2 LEDs
  • Works with 4 LEDs
  • Works with 8 LEDs
  • Works with 16 LEDs
• 2: Linear (e.g. LED strip)
  • Works with 4 LEDs
  • Works with 8 LEDs
  • Works with 16 LEDs
• 3: Square Matrix (works best with a square number of LEDs)
  • Works with 9x9=36 LEDs
  • Works with 9x9+1=37 LEDs

Tried a few scenarios and it works alright.
