Example worker + R2 multipart upload

See my blog post for more information.

This is a simple vanilla js example of a cloudflare worker that uses the aws-sdk to upload multipart files to upload large files to a R2. I've also included a simple html file to demonstrate how to create a client side form that uploads files using the worker.

You might find this useful if you plan on uploading files larger than 5GB to R2.
