List of languages to use for TEXT_DETECTION. In most cases,
an empty value yields the best results since it enables
automatic language detection. For languages based on the Latin
alphabet, setting language_hints is not needed. In rare
cases, when the language of the text in the image is known,
setting a hint will help get better results (although it will
be a significant hindrance if the hint is wrong). Text
detection returns an error if one or more of the specified
languages is not one of the supported languages
