l18n: Internationalization for pytz timezones and territories

l18n is a Python library providing internationalization (i18n) and localization (l10n) services specifically for `pytz` timezones and territory names. It offers lazy translations for names used for localization purposes, such as cities and full timezone names, by fetching them from the CLDR (Unicode's Common Locale Data Repository) database. The latest version, 2021.3, was released in November 2021. Its versioning strategy aims to align with `pytz` releases to ensure consistency with timezone names.
