-Download static files (PDFs, images, archives, etc.) directly.

-This extractor runs AFTER chrome_session and checks the Content-Type header
-from chrome_session/response_headers.json to determine if the URL points to
-a static file that should be downloaded directly.
-
-Other extractors check for the presence of this extractor's output directory
-to know if they should skip (since Chrome-based extractors can't meaningfully
-process static files like PDFs, images, etc.).

-Usage: on_Snapshot__21_staticfile.py --url=<url> --snapshot-id=<uuid>
-Output: Downloads file to staticfile/<filename>

-Environment variables:
-    STATICFILE_TIMEOUT: Timeout in seconds (default: 300)
-    STATICFILE_MAX_SIZE: Maximum file size in bytes (default: 1GB)
