AI Summary: Implement a persistence mechanism for the hexagonal map generator. The goal is to allow users to save and load generated maps, preserving their terrain types and points of interest. The simplest approach should be prioritized.

AI Summary: Implement import and export functionality for hexagonal maps, likely using JSON as the data format. This involves designing a JSON schema to represent the map data (hexagon coordinates, terrain types, points of interest, etc.), and then creating functions to read and write map data to/from JSON files.
