Adding SauceBindings-enabled Visual tests

[mmerrell]

I wanted to show some examples of Visual tests with the Sauce Bindings libraries. I still need to work on page sync--sometimes the pages don't load before the screenshot is taken.

LGTM !

Only thing that is missing is CI integration.
It will help us to ensure that the example is working as we expect.
Example: https://github.com/saucelabs/visual-examples/blob/main/.github/workflows/test.yml#L71-L84 (you may need to rebase first)

I see this more as an example of Sauce Bindings than visual, so I think this should live in a "sauce-bindings-examples" repo.

I don't fully agree. The examples are meant to show how to use Sauce Visual with all kind of frameworks. Sauce Bindings is one of them.
@mmerrell , can you also update the docs, I can help if needed, with a new page for the SB integration, explaining how to integrate this into an existing SB framework?
