I'm working on the implementation of Maps in our application. Internally, we identify states as ISO3166's subdivision codes. It seems that this codes do not always match the "hc-key" provided in some maps. For example, for Argentina:

https://code.highcharts.com/mapdata/countries/ar/ar-all.js
"features": [
        {
            "type": "Feature",
            "id": "AR.TF",
            "properties": {
                ...
                "hc-key": "ar-tf",
                ...
                "woe-name": "Tierra del Fuego",
 ...

While in the ISO, the code is different:

https://www.iso.org/obp/ui/#iso:code:3166:AR
Tierra del Fuego -> "AR-V"

"ar-tf" != "AR-V". In general, in US states the only difference is the letter case (it's lowercase for hc-key, while it's upper case to ISO).

Can we add the ISO subdivisionCode in your provided Maps, maybe as a new metadata key?
