Issue 1:
react-select has a couple of typings issues, I think.

OptionRendererHandler, and ValueRendererHandler incorrectly specify option: Option<TValue> when it should be option: TValue.

Debugging the callback shows that the raw/original object is sent to these handlers, not one wrapped in an Option<T>.

npm 5.5.1

node 8.9.1

Any workaround?
