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](https://cloud.google.com/vision/docs/languages).
