Subject: [PATCH] feat: support 1080p for anon downloading

This change enables anonymous users to download videos in 1080p resolution.

By adding the try_look=1 parameter to the /x/player/playurl API call for unauthenticated requests, we can access higher-quality video streams that are otherwise unavailable to users who are not logged in.
