Export more types from hooks

[AlexHayton]

So that downstream projects can check against these types in their own code.

E.g.

import { usePlane, PlaneProps } from "use-cannon";

export const Plane: FunctionComponent<PlaneProps> = (props) => {
  const [ref] = usePlane(() => ({ mass: 0, ...props }));
  return (
    <mesh ref={ref} receiveShadow>
      {props.children}
    </mesh>
  );
}

For now I've had to create a types.ts and duplicate a lot of the types from hooks.ts to get there... but if the types were simply exported this would be much easier and more maintainable in my project...

Looks good, we should have already been doing this. Merged and released in use-cannon@0.5.2
