TS support

[komarovalexander]

Hi, it would be great if this component has a TS declaration file. Now I have an error in my react ts project:

Could not find a declaration file for module 'rc-pager'. /node_modules/rc-pager/lib/index.js' implicitly has an 'any' type. Try npm install @types/rc-pager if it exists or add a new declaration (.d.ts) file containing declare module 'rc-pager';
