Disable input handling in a non-tty environment

/node_modules/ink/index.js:61

Never seen this one before and googling didn’t help much - what’s going on here? It’s preventing me from running this example from your docs:

`const {h, render, Component} = require(‘ink’);

class Counter extends Component { constructor() { super();

	this.state = {
		i: 0
	};
}

render(props, state) {
	return `Iteration #${state.i}`;
}

componentDidMount() {
	this.timer = setInterval(() => {
		this.setState({
			i: this.state.i + 1
		});
	}, 100);
}

componentWillUnmount() {
	clearInterval(this.timer);
}

}

const unmount = render(<Counter/>);

setTimeout(() => { // Enough counting unmount(); }, 1000);`

Fixed via #42. Will close the issue when a release is out.
