Iran has wrong language code

[Goran M.]

Iran data contains:

       "languages": {
            "per": "Persian"
        },

But that's 639-2/B code, correct 639-3 code would be "fas", here is data collected from official ISO sites:

{
    "639-1": "fa",
    "639-2": "fas",
    "639-2/B": "per",
    "639-3": "fas",
    "family": "Indo-European",
    "name": "Persian (Farsi)"
}
