add an entity culling mod

[hidden horizon]

Basically entity culling for better performance

[visual ravine]

on 1.16.5+ you can add that mod with /modloading and for 1.7.10, 1.8.9 and 1.12.2 you have to wait for them to add forge modloading and that will take a lot of time because lunar uses java 17 instead of java 8 on these versions so most mods would crash if you loaded them

and it was already suggested for 1.8.9 I think
