Reproduction steps

We have found the issue regarding MoveColorTemperature and StepColorTemperature. If the light receives the above command and ColorTemperatureMaximum is 0, the light will not take any action. The light should adjust its color temperature value according to the spec description.

ColorTemperatureMinimumMireds Field
If the ColorTemperatureMinimumMireds field is set to 0, ColorTempPhysicalMinMireds SHALL 
be used as the lower bound for the ColorTemperatureMireds attribute.

ColorTemperatureMaximumMireds Field
If the ColorTemperatureMaximum Mireds field is set to 0, ColorTempPhysicalMaxMireds 
SHALL be used as the upper bound for the ColorTemperatureMireds attribute.

But the SDK currently does not handle ColorTemperatureMaximum is 0.
