Suggestion: Nested advanced condition

[secretmeister2]

While trying to use this I realized that something that would be very useful would be to be able to have nested AdvancedModifierConditions, so I wrote my own.

class_name NestedCondition
extends AdvancedModifierCondition
## This condition is only if all the nested conditions are true. 
## (If inverted, instead returns true if all nested conditions are false)
@export var conditions: Array[AdvancedModifierCondition]
var noise:FastNoiseLite
func is_condition_met(grid: GaeaGrid, cell) -> bool:
	for condition in conditions:
		# Sets child noise seeds to selfs noise seed
		if condition.get("noise") != null and condition.get("noise") is FastNoiseLite:
			condition.noise.seed = noise.seed
		# Checks if the condition is met
		if not condition.is_condition_met(grid, cell):
			return (mode!=Mode.NORMAL)
	# If none of them return false, return true (or opposite if inverted)
	return (mode==Mode.NORMAL)

This allows for much more advanced and customized generation. I don't quite know how to properly do the noise offsetting, that is the part that I feel could be vastly improved.

Hey! If you can make a PR for it I'd appreciate it, but rn I'm working on a new version of Gaea so I'm not adding stuff anymore.
