Create a way to browse packed resources inside .pck file

Godot version:
3.1

Issue description:

I have a directory called Levels with a bunch of json files I use as level templates. While developing I used Directory to iterate through them and load them. But when I export the project there is no (known to me) way to do this, so I end up with an empty list.

Steps to reproduce:

Minimal reproduction project:

I read this and using this. Can you please elaborate a little bit on how can I iterate through resources in a directory inside a .pck file?

A workaround for now is to generate a text file containing a list of paths in a directory, and making sure it's exported using a non-resource export filter (like *.txt). This file can be generated in GDScript using an editor plugin, or using a shell or Batch script. These paths can then be read and used in other scripts.

This does not negate the bug (non-obvious Directory behavior), but you can also try to make a non-resource file a resource:

Yes, I understand the possible workaround and is well aware of export options. I reported this because I believe Directory should behave more consistently.

I cannot replicate:

extends Resource
class_name FileExt

static func list_files_in_directory(path, filter):
	var files = []
	var dir = Directory.new()
	dir.open(path)
	dir.list_dir_begin()

	while true:
		var file = dir.get_next()
		if file == "":
			break
		elif filter:
			if file.ends_with(filter):
				files.append(file)
		else:
			files.append(file)

	return files

calling with ("res://jsonfiles/", ".json") will list all json files correctly

You do have to make sure the files make it into the pck file:

or at least *.json
