Support for Brazilian Portuguese

[lucianor]

Portuguese is a language that is spoken in many countries, but primarily in Portugal and Brazil: Wikipedia

Brazilian Portuguese has many differences to the Portuguese spoken in Portugal. It's very common to have translations for both variations of the language, since Brazil accounts for 203M people, with 58M people speaking the variation closely to the one spoken in Portugal (Angola and Mozambique for example).

However, Argos does not have a different set for Brazilian Portuguese, just Portuguese. Hence, this is a feature request to include this language variation as part of the training set and provide a package for it.
