Explore using Resemble.js for image diffing

[jackjocross]

I recently came across Resemble.js (https://github.com/rsmbl/Resemble.js) and noticed it offers a few advantages over pixelmatch, namely:

• Can run image diffing in the browser, removing the need for Cypress browser <-> server communication overhead
• Tuned for image diffing rather than pixel matching, allowing for less false positives

I think we should explore using Resemble.js for image diffing and see if it would be worth the breaking change.
