Update README.md

- Modified `download_single_file` to check for an existing partially downloaded file
- If present, uses HTTP Range headers to resume the download from the last byte
- Opens file in append mode rather than overwriting it
- Handles HTTP 206 Partial Content and 416 Range Not Satisfiable responses
- Updates progress bar and download state accordingly during resumed downloads
