Kleur crashes when there's a global variable keys

Hi! My app uses global.keys constant. Unfortunately, it conflicts with Kleur internal magic.

function init(key) {
	return function (txt) {
		let isChain = !!this.keys; // <<<
		...
	};
}

As global.keys becomes something different:

this.keys.includes is not a function
    at /.../node_modules/kleur/index.js:95:26

I guess that’s how you detect chaining. Is it possible to use "use strict" pragma and check if this is undefined instead of relying on global object field (which is not safe for libraries)?

No problem. This way it works for me, yes.

Released in v3.0.2 – thank you~!
