If a relative value is found in an hsl() or hsla() string, it will preserve those relative prefixes and all the values in the array will be strings instead of numbers (in all other cases it will be populated with numbers).
		 * @param {(string|number)} v The value the should be parsed which could be a string like #9F0 or rgb(255,102,51) or rgba(255,0,0,0.5) or it could be a number like 0xFF00CC or even a named color like red, blue, purple, etc.
		 * @param {(string)} format If "hsl", an hsl() or hsla() value will be returned instead of rgb() or rgba(). Or if "number", then a numeric value will be returned, like 0xFF0000. Default is rgb.
		 * @return {(array|number)} An array containing red, green, and blue (and optionally alpha) in that order, or if the format parameter was "hsl", the array will contain hue, saturation and lightness (and optionally alpha) in that order. Or if "format" is defined as "number", it'll return a number like 0xFF0000. Always numbers unless there's a relative prefix found in an hsl() or hsla() string and "format" is "hsl".
