AdvancedAdvancementSave

This modification enables the saving of player achievement data files and the scoreboard file (scoreboard.dat) at the precise moment when a player completes any achievement criteria. All save operations are executed in a multi-threaded environment with thread safety guarantees, which prevents direct impact on server performance and avoids lag issues.

The modification was specifically designed for speedrunners using the BlazeandCave's Advancements Pack, ensuring reliable progress saving during intense gaming sessions.
