Suggestion: Add ISO 3166-2 code column

[natydev]

In CSV data should be present ISO 3166-2 code that identify a province/state relative to a country.

https://en.wikipedia.org/wiki/ISO_3166-2

That will be useful to filter and/or identify unique country or province (or state).

example actual data:

Province/State | Country/Region |
---------------------------------
Beijing        | Mainland China |
Guangxi        | Mainland China |
Chicago, IL    | US             |
               | France         |
Padua          | Italy          |

example with ISO 3166-2:

Province/State | ISO 3166-2 | Country/Region |
----------------------------------------------
Beijing        | CN-BJ      | Mainland China | 
Guangxi        | CN-GX      | Mainland China |
Chicago, IL    | US-IL      | US             |
               | FR         | France         |
Padua          | IT-PD      | Italy          |

Best of all, however, is the "ISO 3166-1 alpha-3" code. If so, it should be used as standard here.

[natydev]

But ISO 3166-1 alpha-3 identify only country, not the province/state.
Instead ISO 3166-2 is complete because identify country with the 2 chars before hyphen (practically those 2 chars are the ISO 3166-1 alpha-2 code) and after hyphen there is the unique code for that province (or state).
In case when province (or state) is not available, only the country code is present.

Thank you for the ideas. We will keep them in mind for building out future capabilities.

Right now we're working on something going in this direction Bost/corona_cases#1 It's a messy work and I'm getting exhausted. Talk to me in about 24 hours. Or have a look in my repo.
