Provide a description that is worded well enough to be understood

When I try to download a playlist from aparat.com I get the error Unsupported URL: https://www.aparat.com/playlist/1256882

Provide verbose output that clearly demonstrates the problem

• Run your yt-dlp command with -vU flag added (yt-dlp -vU <your command line>)
• If using API, add 'verbose': True to YoutubeDL params instead
• Copy the WHOLE output (starting with [debug] Command-line config) and insert it below
