title: Upload image URI to Cloudinary
body: <p>I've done some looking at the Cloudinary API and upload examples for NodeJS, and it looks like the server-side uploads use a file path. Meanwhile, the client-side uploads require a frontend input tag. I already have a frontend for users to select and crop a picture to their liking, and this gives me a data URI. I'd like to save this file to Cloudinary without having to use their built in frontend option. Is this possible? This would basically mean that I would be able to call some kind of upload function that can take a URI or file blob.</p>
