Add option to customize white LED temperature

[maganuk]

Is your feature request related to a problem? Please describe.
When auto calculate is set to Accurate or when changing the Color temperature it is assumed that the white led is a cool white led and all calculations are done in accordance with that which leads to inaccurate results. For example, I have a RGBWW strip, which means that the white led is actually warm white. I have to set the Color temperature to cool to get the warm white Color. This is not very intuitive.

Describe the solution you'd like
It would be great if we could set the Color temperature of the white led in the white management section. All calculations involving the white led should be done based on the Color temperature set.

Describe alternatives you've considered
The only way currently that I have found to work around this issue is to manually find the correct Color temperature or create a preset.

My bad, should have looked at the White Balance Correction section.
