Make country_code_to_region_code_map public

This can assist in building better phone HTML inputs.

I see how this indeed can be useful for the described use case.

I have checked libphonenumber and it exposes this data publicly.

UPDATE: After reconsidering: this function should be then be made to show up in the documentation. I would also think to expose it through a different, already public, module.

I can do this (and the docs).
Which module would you recommend?

@szymon-jez Since my motivation for this was to afford building dropdowns for region selector for phone inputs, I think it would be good to add a function that gives us these options.

The reason for this is that we can build this options list at compile time.

What do you think?

UPDATE: Ignore that suggestion. Such a function should use Cldr.Territory and similar, which would bloat this library.

@szymon-jez It is ready for re-review
