In-built method for easier adding separators in strings with large numbers.

[InigoMonotoya]

Some day i wanted to improve readability of my score counter, by adding dots after thousands, millions, etc., to look like this: "Score: 12.345.678", instead of: "Score: 12345678". But, turns out, that there is no simple way of doing this in Godot. So i wrote a function to do that, and i thought that maybe someone more capable than me can make it into a built-in method, to make it easier for everyone. Without further adue, here it is:

func separators(string: String, separator: String = ".", interval: int = 3):
	var finalString: String = ""
	for i in len(string):
		#adding chars from the back of original string
		finalString = string[len(string) - (i + 1)] + finalString
		#interval is number of chars between separators
		if (i + 1) % interval == 0:
			finalString = separator + finalString
	#removing possible separator in front
	if finalString.begins_with(separator):
		finalString = finalString.substr(len(separator))
	return finalString

For loop adds characters from the end of original string and every third run (assuming interval == 3) puts a separator in beginning. After loop finishes, function runs the if statement, to avoid profanities like ".123.456.789". I imagine calling this method would look like this:

print("12345678".put_separators(".", 3)) # Prints "12.345.678"

I don't know if anybody needs this and frankly, my dear, i don't give a damn, so i'm happy to just leave it here, as is.
