Fake wallet does not render SVG icons

[steveluscher]

We should consider making the fake wallet app able to render any reasonable kind of icon, or should specify which image formats are allowed. Right now it doesn't appear to render SVG files.

I'll add support for SVG rendering to fakewallet. That seems like a reasonable expectation to set, and fake wallet will, for better or worse, end up implicitly defining much of the standard implementation.

I opened a PR regarding this

#73

Coil library will make it easier to support svg and regular images at the same time on the fakewallet app ( I guess at the end of the day the wallet developer can use any library)

Ideally the AuthorizeRequest can have a getIdentifyType method which lets the wallet know that it needs to display a svg, png, gif, etc.
