Adjust subtitle delay in player

[morkyy]

Describe the feature you'd like

Similar to how we can adjust the playback speed of a file in the player (which was added recently). It would be great if there was another button that would allow us to adjust subtitle delay. It is very common to have subtitles that are not as accurate and are out of sync (especially for older tv shows). Allowing the user to adjust this in the player would provide a much better user experience and would avoid the whole trial and error process of searching for new subs, uploading them to Jellyfin and then test if they are accurate.

To keep the player from not feeling as cluttered the button could only show up if a subtitle track is selected, or maybe include it in a sub menu along with the subtitle selection.

+1 , an unfortunate necessity sometimes, I find myself looking for this feature on the ATV client
