[xDivisionByZerox]

Fill the states dataset for the locale cz.
In the Czech Republic "states" are called "regions". They are not the same but serve the same purpose for our data.

I was not able to find anything regarding state abbreviations. Should I simply copy the existing dataset in that case?

Instead of copying it you can import it and export it afterwards (with a comment why).
