Changelog:
- Added a new option to the Spawners System (Custom-Spawner-System: true, Means the Spigot custom spawner system will be active. You can now disable it if you have a custom spawners system)
- Minor tiles entities optimizations

Keep in mind, Changing spawners values may not take effect until the player breaks and replaces their spawners. That's not something i control at the moment and is a limitation from Spigot itself. If old spawners are not broken they *may* keep their old values.
If you haven't changed your spawners values, That won't be needed.

- Optimized chunk loading when players teleport
- Fixed some lightning bugs that could cause client and server de-sync from Paper
