maxWidth doesn't appear to be working. It simply grows beyond it's bounds.

var bins = [
            { width: 10, height: 20 },
            { width: 1000, height: 100 },
            { width: 50, height: 19 },
            { width: 50, height: 19 },
            { width: 50, height: 19 },
            { width: 50, height: 19 },
            { width: 50, height: 19 },
            { width: 50, height: 19 },
            { width: 50, height: 19 },
            { width: 50, height: 19 },
            { width: 50, height: 19 },
            { width: 50, height: 19 },
        ];

        var result = pack(bins, { maxWidth: 144});
        console.log(result);

        result.items.forEach((item: any) => {
            console.log(item);
        });

    {
      width: 1000,
      height: 215,
      items: [
        { width: 1000, height: 100, item: [Object], x: 0, y: 0 },
        { width: 50, height: 19, item: [Object], x: 0, y: 100 }, 
        { width: 50, height: 19, item: [Object], x: 50, y: 100 },
        { width: 50, height: 19, item: [Object], x: 0, y: 119 }, 
        { width: 50, height: 19, item: [Object], x: 50, y: 119 },
        { width: 50, height: 19, item: [Object], x: 0, y: 138 },
        { width: 50, height: 19, item: [Object], x: 50, y: 138 },
        { width: 50, height: 19, item: [Object], x: 0, y: 157 },
        { width: 50, height: 19, item: [Object], x: 50, y: 157 },
        { width: 50, height: 19, item: [Object], x: 0, y: 176 },
        { width: 50, height: 19, item: [Object], x: 50, y: 176 },
        { width: 10, height: 20, item: [Object], x: 0, y: 195 }
      ]
    }
    

It doesn't return any form of error or explicitly call out which ones go beyond packing comfortably within the constraint
