Add support for image upload/serve api (cloudflare-images)

[kingmesal]

It would be great if like the KV store I could upload files when running in wrangler as this would allow me to much more quickly build my applications locally which allow image upload services.

https://developers.cloudflare.com/images/cloudflare-images/

If running locally via wrangler, maybe providing a local path to store / retrieve the images.

Hey! 👋 Thanks for the feature request. Should be possible to implement this along with #241.
