Extending Coil

I was recently working on showing thumbnails for files, and found that the image loading code was surprisingly complex. I load thumbnails from my backend service via an SDK, which means I don’t have a simple URI that I can provide to an image loading library to load images. Added to that is the fact that I usually pass around a lightweight file id to represent files within my app, but my backend also requires a revision to generate a thumbnail, even though I always simply want the latest revision.
