Convert an HSV value to RGB using a mathematically straight spectrum.
This "spectrum" will have more green and blue than a "rainbow", and less yellow and orange.

- Note
- This function wraps hsv2rgb_raw() and rescales the hue value to fit the smaller range.
- Parameters
-
hsv | CHSV struct to convert to RGB. Max hue supported is HUE_MAX_SPECTRUM |
rgb | CRGB struct to store the result of the conversion (will be modified) |
