Change CirclePicker selected style

Is there any way to override the selected style for the CirclePicker? I'm not seeing any active or selected class on the element once selected.

Also, typescript complains when I try to add the `style` prop to the picker.

Start by locating the CirclePicker implementation and its type definitions. Reproduce the missing selected-style override and the TypeScript error when passing style; the work is done when selected styling can be overridden and the style prop is accepted by TypeScript.
