/**
 * Converts a HslColor or HslaColor object to a color string.
 * This util is useful in case you only know on runtime which color object is
 * used. Otherwise we recommend to rely on `hsl` or `hsla`.
 *
 * @example
 * // Styles as object usage
 * const styles = {
 *   background: hslToColorString({ hue: 240, saturation: 1, lightness: 0.5 }),
 *   background: hslToColorString({ hue: 360, saturation: 0.75, lightness: 0.4, alpha: 0.72 }),
 * }
 *
 * // styled-components usage
 * const div = styled.div`
 *   background: ${hslToColorString({ hue: 240, saturation: 1, lightness: 0.5 })};
 *   background: ${hslToColorString({ hue: 360, saturation: 0.75, lightness: 0.4, alpha: 0.72 })};
 * `
 *
 * // CSS in JS Output
 * element {
 *   background: "#00f";
 *   background: "rgba(179,25,25,0.72)";
 * }
