1.Fix the issue with limiting dense entities where limiting Slimes causes excessive splitting (optimizing lag):
Previously, when limiting Slimes, they would split into multiple small Slimes, causing excessive splitting and potential server lag.
Now, when removing Slimes, they will not split into small Slimes, thus optimizing performance and reducing lag.
2.World entity count restrictions and whitelist/blacklist entity type names for sweeping are now case-insensitive:
The entity type names used in world entity count restrictions and whitelist/blacklist configurations for sweeping are now case-insensitive.
This means you can use any case (e.g., Slime, slime, SLIME, SleMe) without worrying about case sensitivity issues.
3.Optimized the implementation of QuickSendMessage (limiting player chat/command usage rate) to use timestamp recording:
The QuickSendMessage feature, which limits the rate at which players can send chat messages or use commands, has been optimized.
Instead of using previous methods, it now records timestamps to track and enforce the rate limits more efficiently.

1.修复限制密集实体时，限制史莱姆会导致大量分裂的特性（优化卡顿），现在密集实体移除史莱姆不会分裂出小史莱姆
2.世界限制实体数量的实体类型名|扫地时的白名单/黑名单的实体类型名，加入了大小写忽略(Slime,slime,SLIME,SleMe【随你便】)
3.优化了QuickSendMessage（限制玩家聊天/指令使用速率的功能）的实现方式，现在是采用记录时间戳的形式
