How to use a background image for slides in v6?

Background Info/Attempts

I've been trying to transition to v6, one thing I've not been able to do is to add a background image to the SlideContainer Component. I am using spectacle-boilerplate and mdx mode.

There's a PR open right now for background images: #849
