Added --quiet argument to suppress progress bars

[rtomek]

Added support for a --quiet option for download-single and download-multiple commands.

After updating to the latest gen3-client.exe file, our python scripts at MIDRC stopped working due to these functions needing an actual terminal window to generate the progress bars, and attempted workarounds to generate a console weren't working. Since this issue only seems to occur when used with a script wrapper, we can assume that the scripter should have a way to track progress (whether they choose to track progress or not is up to them).

New Features

Added a --quiet flag for download-single and download-multiple

Breaking Changes

None

Bug Fixes

If a progress bar could not be generated due to not finding a suitable terminal window, gen3-client would create a zero byte file and exit.

Improvements

Dependency updates

Deployment changes

We may need to update web docs to notify users of this new flag. The flag documentation when using e.g. ./gen3-client download-single --help in included with this PR.

Pull request overview

This PR adds a --quiet flag to the download-single and download-multiple commands to suppress progress bar output. This addresses an issue where Python scripts calling gen3-client would fail when progress bars couldn't be rendered due to the absence of a terminal window.

Key changes:

• Added --quiet flag to both download commands with conditional logic to skip progress bar initialization and updates
• Modified downloadFile and batchDownload functions to accept a quiet parameter and conditionally create progress bars
