HB says Color Temperature exceeds max value when it doesn't
**Describe The Bug:**
The homebridge logs are filled with this warning:
`[10/14/2021, 2:49:42 PM] [homebridge-tplink-smarthome] This plugin generated a warning from the characteristic 'Color Temperature': characteristic was supplied illegal value: number 400 exceeded maximum of 370. See https://git.io/JtMGR for more info.`

According to https://developers.homebridge.io/#/characteristic/ColorTemperature, the max value for Color Temperature is 500, so 400 should be valid.  The maximum value of 370 seems to conflict with the documentation.

**To Reproduce:**
Install the `homebridge-tplink-smarthome` plugin and add a color bulb (KL130)

**Expected behavior:**
Warning should go away if the max value in the documentation is true.
