better loading in util.read_localized_resource

The other code kinda assumed that we can turn the resource path into a
package by replacing the slashes (path separators) with dots. That
turned out to not really work in the end, especially if the resource
subfolders don't have a __init__.py in there.

This uses the .files() API (available in Python 3.9 and backported in
importlib_resources) to better handle folders in the resources.
