How to fetch presigned URLs for multipart upload with object_store crate?

[jayatisarkar]

Currently, there is support for fetching presigned URLs to upload an entire object to s3 via this trait: https://docs.rs/object_store/latest/object_store/signer/trait.Signer.html

What is the recommended way of doing this for multipart uploads where a presigned URL can be generated for each part similar to the AWS S3 SDK?
