Ivory Coast region codes aren't ISO-3166-2 compliant

[Portur]

Hi, It seems the region codes for Ivory Coast aren't compliant with the ISO-3166 syntax.

The expectation is to have a syntax like CI-XX but the result is like CI-XX-XX.

Usage

const geojsonPlaces = require("geojson-places");
geojsonPlaces.getRegionsByCountryAlpha2('CI');

Result (only invalids)

    "country_a2": "CI",
    "region_code": "CI-CM-SC",
