Inconsistent colorthief imports leads to crash in tests

[tbragaf]

I'm creating my own function which internally uses the GetPalette function.
When using it in development mode, I can make it work simply by:

import Colorthief from "colorthief";

function getPaletteFromImage(img: HTMLImageElement, colorsCount: number, quality: number): string[] {
    const colorthief = new Colorthief();
    var palette = colorthief.getPalette(img, colorsCount, quality);
    
    // ... 
}

However, this fails when running tests stating the Colorthief is not defined .

I noticed that you export the ColorThief function as a default in https://github.com/lokesh/color-thief/blob/master/src/color-thief.js#L147.
You then use it by creating an object in https://github.com/lokesh/color-thief/blob/master/examples/js/demo.js#L1.

But in your tests, you don't create any object, and simply use a function. https://github.com/lokesh/color-thief/blob/master/test/node-test.js#L17

Why is that?

Thank you,
