Grow and harvest a marsh crop.

At some point, either before or after the Wetland Walkers have been created, Wyatt Jones will prompt the player with exploring into the marsh to grow and harvest a marsh crop.
 * Wyatt: My research into the marsh flora has been progressing superbly.
 * Wyatt: However, I would love to study edible crops native to the marsh biome. Can you assist me by cultivating a marsh crop?
 * Option 1: Nah, I'm too busy.
 * Option 2: Sure, I'll help!

To complete the job, the player must first find some marsh seeds in the nests throughout that region. Then, they must use an Improved Hoe to till an area of farmland, plant the seeds, and cultivate them to harvest. Once the first crop is harvested, the job will be complete, and Wyatt will ask the player to tell him about the cultivation.
