Expected Behavior vs Actual Behavior

Previously, it was possible to do the following without re-encoding:
spotdl --log-level DEBUG --format opus --bitrate auto "Dokho - Limania".
spotdl would download best WEBM (usually 251) and copy the data to .opus without re-encoding.

Currently, it always defaults to .mp4 stream and then converts it to .opus.
Also, --bitrate auto is broken and fails conversion #2342

I made attempts to pass --yt-dlp-args "--format 251" and hardcode ytdl_format in mase.py:99 without success. It results in "Requested format is not available. Use --list-formats for a list of available formats" from YouTubeDL.py:2987.
Passing the same URL to fresh external instance of yt-dlp works as expected.

Upgrading embedded yt-dlp to 2025.3.31 fixes both issues.
