React 17 support

[mtmacdonald]

Hi, please can we have React 17 support so I don't get this peer dependency warning upon npm install in my React 17 projects. Thanks!

npm WARN react-input-autosize@2.2.2 requires a peer of react@^0.14.9 || ^15.3.0 || ^16.0.0-rc || ^16.0 but none is installed. You must install peer dependencies yourself

There is now a PR for that at #175
