Convert HSV values to RGB. This is essentially the hsv2rgb function found in pqx/color-functions, however this module returns an array rather than an dictionary.
$ npm install hsv-rgb
rgb(h, s, v)
var rgb = require('hsv-rgb')
rgb(36, 76, 86)
> [219, 153, 53]
rgb.apply(null, [36, 76, 86])
> [219, 153, 53]
