Feat: Add Progress Bars for Long-Running Processes

[berntpopp]

Description:
Implement progress bars (e.g., using tqdm) for long-running tasks such as fetching large datasets, downloading multiple files, or processing large TSV/JSON files. This will improve user experience by providing feedback on the task's progress.

Proposed Solution:

• Use tqdm or a similar library to implement progress bars.
• Display progress bars for tasks that take longer than a configurable threshold (e.g., 5 seconds).
• Ensure that progress bars work with both CLI and non-interactive environments (e.g., logging).
