 * Create authenticated direct upload URL V2

 * Direct uploads allow users to upload images without API keys. A common use case are web apps, client-side applications, or mobile devices where users upload content directly to Cloudflare Images. This method creates a draft record for a future image. It returns an upload URL and an image identifier. To verify if the image itself has been uploaded, send an image details request (accounts/:account_identifier/images/v1/:identifier), and check that the `draft: true` property is not present.
