Improve UI Testing

Add end-to-end testing using cypress. #55

Breaking changes

1. No longer listen to images with data-action="zoom" on initialization #68.
2. Remove defaultZoomable option.

All of the following will no longer make images zoomable:

1. Simply include a script.

2. Initialize a Zooming instance:

new Zooming()

3. Initialize a Zooming instance with defaultZoomable:

new Zooming({
    defaultZoomable: '.img-zoomable'
})

Instead, please ALWAYS call .listen() on target images after creating a Zooming instance:

const zooming = new Zooming({
    // options...
})

zooming.listen('.img-zoomable')
