feat: Add InCurrentVersion property to CommonRecord and implement comparer

Added the InCurrentVersion field to the DivingFish and Lxns data models to indicate whether a song is available in the current version.
Also made CommonRecord implement the IComparer interface, providing comparison logic for sorting by DXRating, LevelValue, and Achievements.
