This reverts commit bd2ec12e0f039c9500ea0dd94e7b2e4f7d168fef. Country is both the data (name, ID, etc) and the container for groups added to the miz, so it can't be used across multiple mission generations. See https://github.com/pydcs/dcs/issues/314 for potential follow up work that would let us do this. Fixes https://github.com/dcs-liberation/dcs_liberation/issues/2864.
