Log some progress indicator for downloading files and docker images

Component

sp1-sdk

Describe the feature you would like

When using cargo prove build --docker I don't see any CPU activity or logging happening, so assumed something was amiss. Turns out that I noticed my network monitor spiking and figured it was the sdk internally pulling the (quite large) sp1 builder image.

sp1/crates/cuda/src/lib.rs

Lines 218 to 221 in 6544380

	// Pull the docker image if it's not present
	if let Err(e) = Command::new("docker").args(["pull", &image_name]).output() {
	return Err(format!("Failed to pull Docker image: {}. Please check your internet connection and Docker permissions.", e).into());
	}

I was on a slower network, so this took minutes to complete.

Also related to #2255 in a way: it was hard to discover why things were hanging after resolving the panic... that file download also took order of minutes for me.

I would like a way to get some indication that a docker image and/or file is being downloaded, if possible, piping the log stream of docker pull so it's visible.

Seems this should be possible as IIUC stderr is how things are generally communicated in the build like here:

sp1/crates/sdk/src/install.rs

Line 108 in 6544380

eprintln!("[sp1] downloaded {} to {:?}", download_url, build_dir.to_str().unwrap(),);

Additional context

Very-nice-to-have: A TUI progress indicator on downloads, perhaps using something like https://docs.rs/indicatif/latest/indicatif/ with streamed download via reqwest::Response::bytes_stream() to stderr if possible.

Example: when missing groth16 artifact, it downloads and prints this nice progress bar
