SwitchProps interface is not exported

[claudvanbarret]

I'm styling switch with styled-components in TypeScript like this:

import styled from "styled-components";
import Switch from "rc-switch";

export const StyledSwitch = styled(Switch)(({ checked, disabled }) => {
  position: "relative",
  borderRadius: "1rem",
  cursor: "pointer",
});

But I'm getting this error.

Exported variable 'StyledSwitch' has or is using name 'SwitchProps' from external module "/Users/claudvanbarret/project/node_modules/rc-switch/lib/index" but cannot be named.ts(4023)

This error can be probably is an issue in TypeScript, but wen can quickly solve this problem by exporting the SwitchProps interface.

I already send a pull request(#56) to fix it.
