 * Radio groups are used to group multiple radio buttons so that make sure that only one will be selected in the group

 * Hierarchies:
 * - `daikin-radio-group` > `daikin-radio`
 * - `daikin-input-group` > `daikin-radio-group` > `daikin-radio`
 *
 * @fires change - A custom event emitted when current checked radio changed.
 *
 * @slot - A slot for radio buttons. Place `daikin-radio` elements here.

 * @example
 *
 * ```js
