Light: Invert set_color_temperature range check

[forderud]

Fixes #125 by changing the logic, so that it fails if the temperature is outside the valid range instead of inside.

Wow crazy this didn't come up earlier, thank you!

No wait a minute, at least my lamps all have as min 4000 and as max 2022
@forderud do you have other values?

This was very odd. I've so far only purchased an Ikea KAJPLATS E27 WS G60 lamp that reports color_temperature_min=153 and color_temperature_max=454. I therefore don't have any other device to compare against.

Could it be an idea to add logic for swapping min/max values to ensure that max is always greater than min? I'm thinking something along these lines...

if color_temperature_min > color_temperature_max:
    color_temperature_min, color_temperature_max = color_temperature_max, color_temperature_min # swap values

I've now updated colorTemperatureMin & colorTemperatureMax accordingly in the associated unit-test. They now pass when testing locally.

I can also add color_temperature_min/color_temperature_max swapping if desired, but will need some advise on where to put the code.
