Better Bedrock Generator

Its now possible to define which block to use as the layer.

[General]
	#A list of dimension ids that this mod should filter based on the 'Act as whitelist' setting.
	#Modded dimensionFilter will need to be added here to be affected.
	#Adding a '=>' behind the dimension id, you can change the layer to another block.
	#Adding nothing will result in default bedrock
	dimensionFilter = ["minecraft:overworld=>minecraft:dirt", "minecraft:the_nether"]
	#Set to false to make the dimension whitelist act as a blacklist.
	isWhitelist = true
