Added support to register fan processing type

[Prunoideae]

CreateEvents.fanProcessing(event => {
    event.create("kubejs:leaves")
        .isValidAt('minecraft:oak_leaves')
        .canProcess("minecraft:dirt")
        .process((stack, level) => [Item.of("clay", stack.count)])
        .morphAirFlow(Color.GREEN_DYE, 0.5, "minecraft:rain", 20)
})

Example video, the processing time is set to 40 in the server config to skip waiting:
