Example generator usage:
use rand::prelude::*;
use mapgen::{MapBuffer, MapFilter};
use mapgen::filter::DrunkardsWalk;
let mut rng = StdRng::seed_from_u64(100);
let gen = DrunkardsWalk::open_area();
let map = gen.modify_map(&mut rng, &MapBuffer::new(80, 50));
assert_eq!(map.width, 80);
assert_eq!(map.height, 50);
