resources/map_gen_settings.lua
--[[ The easiest way to create a preset to add to this file is to use factorio itself. Create a new world
    (vanilla, not scenario) and configure the settings you want. When you launch the game, you can run the following:
    /c
    local str = serpent.block(game.surfaces.nauvis.map_gen_settings)
    helpers.write_file('map_gen_settings.lua', str)

    This will output a file with a table that you can add to this resources file or into your specific map.
    In either case, make sure to set seed to nil unless you want your map to be *exactly* the same each time.
    The expectation is that all changes that deviate from default generation are noted.

    Water:
        frequency: (water scale), defines "Terrain segmentation" := 1 / water.frequency
        richness: 0/1, defines the presence of water on map
        size: (water coverage), defines the amount of water on map
