Expose more final types

[roydukkey]

Though it is currently possibly to determine most types from the default export...

import cliui from 'cliui';

type UI = ReturnType<typeof cliui>;
type UIOptions = Parameters<typeof cliui>[0];

...these types are rather finicky. It would be great if more finalized types were exported from this package.

The current types you are seeing were not intended to be published, which explains why they are a bit lacking, but they may go away rather than be improved! 😢
