 * Helper for targeting rules in a style block generated by polished modules that need !important-level specificity. Can optionally specify a rule (or rules) to target specific rules.

 * @example
 * // Styles as object usage
 * const styles = {
 *   ...important(cover())
 * }
 *
 * // styled-components usage
 * const div = styled.div`
 *   ${important(cover())}
 * `
 *
 * // CSS as JS Output
 *
 * div: {
 *   'position': 'absolute !important',
 *   'top': '0 !important',
 *   'right: '0 !important',
 *   'bottom': '0 !important',
 *   'left: '0 !important'
