Currently the `Translator` fall backs based on the locale separator (eg `es_AR` to `es`), but the ICU data contains parent locales (eg `es_AR` is a child of `es_419`, as is `es_BO`, `es_EC` etc).

This makes use of the ICU data to add add in these fallbacks. This means the specific locales can be used, but the translations can stored in these groupings (eg `es_419` for Latin American Spanish), as well as adding other sensible fallbacks (eg Cape Verdean Portuguese to `pt_PT`).
