IsaacSaveManager 2.3

IsaacSaveManager 2.3

Nearing the last patch of adjustments I'd wanna make to this manager. Pretty much the only thing left would be serialization if I ever get around to it

• Glowing Hourglass support for going back to the previous floor
• Support for Tainted Lazarus on MC_POST_PLAYER_INIT
• Fix Myosotis not working as it was only checking pickups in the previous floor's room instead of all the previous floor's save data
• Fix Glowing Hourglass not working entirely as intended on REPENTOGON as clearing rooms would trigger a new hourglass backup. On REPENTOGON, the hourglass backup save now separates its backups into two slots, same as what the RGON hourglass callbacks utilize
• SaveManager.Utility.AddDefaultRoomData now actually adds room data. Was previously adding temp data
• Add SaveManger.Utility.AddDefaultTempData
• When validating the save data for JSON, checks for validating the index and value have been combined into one loop instead of separate loops. Should help reduce time it takes to save a tad
