GDScript: PoolDictionaryArray with predefined keys and values

# This is a method of creating an array of dictionaries all of which are set to default keys and values,
# which means you can now quickly set up large amounts of data quickly through the inspector

tool # will not work if you don't/can't make the script a tool
extends Node # OR WHATEVER
