Incorrect Hue Output?
I've noticed that SmartThings was having an issue with Hues over 100 being sent to one of my devices from Homebridge-Smartthings and investigated it. [SmartThings documentation ](http://docs.smartthings.com/en/latest/capabilities-reference.html?highlight=color#color-control) says this value should be between 0-100%, but it is being sent as a value from 0-360. 

A personal test dividing the output  of a hue by 3.6 to convert the value to percentage proved successful.

Any chance this could be fixed for the public build?
