Errors in console when using imageSettings without width/height

[guido-visser]

When I add

{
src: "URL_TO_IMAGE.svg",
excavate: true
}

I get errors in the console, saying that the width and height in the imageSettings prop are required, but the docs say that the default is 10%

It's a little messy. You really should be passing in these values as the fallback is really dumb and will not scale images evenly (will always make them square). It's really just there to prevent things from exploding. I should update the docs to be clearer.
