Color reading is now implemented to the sensor driver. I'm not sure if the onboard LED at the Flora sensor board can be turned completely off.

I'm using currently 700 ms integration time because shorter ones don't give reliable results (impacts to resolution and sensitivity). I'll do next some testing and code the automatic color change for the leds using the sensor values.

Edit: Some kind of polling is now too implemented. I'll make a short demo video at some point to show how well (or badly) the sensor performs
