KL130 temperature range (2500 - 9000K) exceeds node limits (2700 - 6500K) - can the range be extended please?

Many thanks for this node. I discovered last night that the temperature range capabilities of my KL130 bulbs significantly exceed the limits set by the node.

Describe the solution you'd like
Permit control of the greater range that the bulb supports

It would likely make sense to remove the manually hardcoded values and use getColorTemperatureRange/colorTemperatureRange instead.
