[Experimental] TheAfterGenerator

This is an experimental plugin, It uses NMS to generate vanilla structures after the world has already been created.

WorldPainter can no longer generate structures using the latest format of the game and even when the program was able to generate them I noticed it would place structures in wrong biomes. TheAfterGenerator provides a way to add those structures back into custom worlds.

Features:
Generate command will generate a structure of your choosing where you are standing if it is applicable to the location.

Process command will iterate through every chunk between the min and max arguments checking to see if it can place a structure in those chunks. The structures will respect the terrain so you will not find ocean monuments in a plains biome. Eyes of ender will also point to where strongholds are generated when using the /process command.

Commands:
/ag generate [Structure] [Random]
/ag process [minBlockX] [minBlockZ] [maxBlockX] [maxBlockZ]

Permissions:
aftergenerator.command

Known Issues:
Ocean ruins, igloos and shipwrecks are disabled because they'll generate at the very bottom of the world if enabled
Villages will not spawn with any paths
The Console will be spammed with
"Trying to mark a block for PostProcessing @ {}, but this operation is not supported." There might be a way to make it not spam this but because you are generating a structure in an already "Finished" chunk rather than a chunk that is currently generating I don't see a way to fix it. Maybe consider it a progress bar instead!
