	Tiny queue data structure.

	The instance is an [`Iterable`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Iteration_protocols), which means you can iterate over the queue front to back with a “for…of” loop, or use spreading to convert the queue to an array. Don't do this unless you really need to though, since it's slow.

	@example
	```
	import Queue = require('yocto-queue');

	const queue = new Queue();

	queue.enqueue('🦄');
	queue.enqueue('🌈');

	console.log(queue.size);
	//=> 2

	console.log(...queue);
	//=> '🦄 🌈'

	console.log(queue.dequeue());
	//=> '🦄'

	console.log(queue.dequeue());
	//=> '🌈'
	```
