Storage queue

This package contains a persistant FIFO queue implementation working with localstorage. It can enqueue and dequeue items, as well as peek the next item without deleting it.

Usage

``ts
import { LocalStorageQueue } from './src/local-storage-queue';

interface Message {
hello: string;
world: number;
}

const queue = new LocalStorageQueue('myQueue');
queue.initialize();

queue.enqueue({
hello: '123',
world: 123
});

queue.enqueue({
hello: '456',
world: 456
});

queue.peek();
// { hello: '123', world: 123 } item still in the queue

queue.dequeue();
// { hello: '123', world: 123 } item deleted from queue

queue.dequeue();
// { hello: '456', world: 456 } item deleted from queue

queue.dequeue();
// null queue is empty
