[Feature Request] AWS S3 upload/download via HTTP

**Describe the new feature request**
Provide a clear and concise description of the feature you are proposing, as well as applicable use cases.

A feature that allows to download or upload files to AWS S3.
We currently have to transfer large files (more than 10MB) to our S3 storage and expresslink does not allow to do that.

**Describe other alternatives you've considered**
Provide a clear and concise description of any alternatives you've considered.

We are currently using a custom solution for that (not iot-expresslink) in which we had to implment chuck based S3 upload and download.

**Additional context**
Add any additional information supporting the request here (screenshots, logs, references, etc.).

The issue names no files, tests, or entry points. Start by reviewing the repository structure and the AWS S3 transfer requirements, including chunked handling for files over 10 MB. Done should include a defined HTTP upload/download workflow and tests covering the supported behavior.
