 * The styled HOC wrapper allows you to create a functional wrapper around a given component which will resolve

 *
 * @example
 * ```tsx
 * export const Toggle = styled(
 *   ToggleBase,
 *   props => ({ root: { background: 'red' }})
 * );
 * ```
 * @param Component - The unstyled base component to render, which receives styles.
 * @param baseStyles - The styles which should be curried with the component.
 * @param getProps - A helper which provides default props.
 * @param customizable - An object which defines which props can be customized using the Customizer.
 * @param pure - A boolean indicating if the component should avoid re-rendering when props haven't changed.
 * Note that pure should not be used on components which allow children, or take in complex objects or
 * arrays as props which could mutate on every render.
