Adding alignment to image upload

[funk101]

I was able to modify the paragraph tool to add text alignment. I need to do the same for the image tool. Can someone supply some code similar to what was posted in this issue? editor-js/paragraph#22
Or is it possible to just include the image in the above code? I see there's a reference to an image:

   * Tool's classes
   */
  imageHolder: 'utd-image__picture',
  caption: 'utd-image__caption',
  link: 'utd-image__link',
}

if so, where would that be, here?

/*Method that specified how to merge two Text blocks.

@param {ParagraphData} data
@public
*/
merge(data) {
let newData = {
text: this.data.text + data.text,
class: this.data.class,
}
this.data = newData
