[Feature Request] Placeholder that displays the number of seconds left until a dungeon cooldown is finished

Greetings, I would like to request a placeholder that outputs the raw number of seconds remaining until a dungeon's cooldown is finished.

For example, if someone is on cooldown for 1 hour, it should output "3600".

This is so it can be used in other placeholders such as %formatter_number_time_<number>% which would convert the time into something more readable like "1h" but I would prefer to handle this with a formatter placeholder for added flexibility, which is why I would like the placeholder to output raw seconds.

Suggested Placeholder: %md_dungeon_[dungeon]_unlock_time_seconds% or %md_dungeon_[dungeon]_unlock_seconds%
