Subject: feat(output): make ffmpeg loglevel configurable

Add --ffmpeg-loglevel so users can choose which ffmpeg messages are
shown during encoding instead of always using the built-in default.

Load the same setting from [output].ffmpeg_loglevel when it is
configured and no CLI value was provided.

Document the new option in the README and man page, and add shell
completion for supported ffmpeg log levels.
