Kelp store age metadata by bulk on a queue, improve API, etc.
Highlights: - Implement storing age metadata by bulk on a queue, with maximum interval and queue length. - "Flexible" initial growth probability. Will provide helper APIs. - Fix various bugs with unsubmerged kelp detection, submerged tip detection, age metadata. - Various optimizations.
