[feat req] upload files directly without compressing into a zip file

[JadianRadiator]

What would you like to be added?

I want to be able to upload files as artifacts directly without compressing them into a zip file.

Why is this needed?

I need it so that I won't have to extract a zip archive before testing a build.
