Ability to download from a GitLab Artifact

[obbardc]

GitLab artifact ZIP URL could be something like https://gitlab.collabora.com/showcases/electronica2022/electronica2022-image-recipes/-/jobs/artifacts/main/download?job=build%20image

Also support authentication using access tokens.

@Razaloc Perhaps you could take a look at how this could work ? I think we'd need to detect that the file to download is a ZIP file and load the ZIP file contents list (at the end of the file) first using an HTTP range request.
