loicleray/WOAH_WAHIS.ReportRetriever ? reverse-engineered prompt

Build me a Python tool that helps people download animal disease outbreak reports from the WOAH WAHIS site. I want a simple command line app that lets me filter by country, region, disease, and a start and end date, then pulls down the matching reports and saves them in easy to use spreadsheet or CSV files.

It should also have a way to fetch and save the available filter options first, so I can see the exact disease and location names I need to use. The app should handle a lot of reports without crashing, save progress as it goes, and be polite with the website so it does not hammer their servers.

If the current WOAH site has changed, please inspect the live docs or pages and update the scraper so it still works. Keep the code clean and make the command line experience straightforward for a non expert.
