Step-generator form of generateMap: yields a GenerationProgress
at every suspension point (between passes and inside the heavy ones), so a
driver can spread the work across frames and show a loading bar. Drive it
with generateMapAsync for the batteries-included version, or iterate it
yourself for custom scheduling. Deterministic — same seed + config produces
the same map as generateMap.
