      Find the most specific localized resource for the given name, extension and locale:

      The file will be searched with locations in the following order, similar to `java.util.ResourceBundle`'s search order:

      - [name]_[language]_[country]_[variant][extension]

      - [name][extension]

      If none of the specific files can be found, a resource descriptor for the default location will be returned.

      Parameters:
        `name` - the name of the file, without localization part nor extension
        `extension` - the file extension (e.g. ".xls")
        `locale` - the current locale (may be `null`)
      Returns:
        the most specific localized resource found
