More Uses For Poisonous Potatoes

In its current state, the Poisonous Potato has very little functionality. The only use for the Poisonous Potato is for the advancement "A Balanced Diet", in which the player must eat every food item. Giving the poor potato a few more uses would help the item feel more incorporated into the game, and give the player a reason to seek it out.

• Poisonous Potatoes can be used in brewing. While a Spider Eye does fit the bill as an item fit for a Potion of Poison, a Poisonous Potato would fit in just as well. This could even be expanded upon with other potions, as a single potion could have multiple items that could be used to make it.
• Poisonous Potatoes can be used to speed up oxidation in Copper Blocks. This has been posted before, but it would be a great way to decrease oxidation speeds without creating unintuitive game mechanics. It could work just like Honey Comb does now, and could even be given an advancement to fit with "Wax On" and "Wax Off".
• Poisonous Potatoes should be used to craft Suspicious Stew with the Poison effect. This would fit in theme with the brewing change above. This change is one of the weaker ones as all Suspicious Stews are made specifically with flowers, instead of a hodgepodge of items like brewing.
