Prehistoric Flowers Specificities

The last snapshot added the "torch flower" which will probably be part of a gallery of prehistoric flowers in 1.20. They lacks utility though, so I offer them some specifities : First, they could be used as a consumable to regenerate and give potion effects for a short time, such as fire resistance for the torchflower. In this logical sequence they could also make it possible to make arrows with effects. Secondly they could be used for trade purposes with the villagers in order to exchange them with interesting pieces of weapons and armor, I also propose the addition of the villager archaeologist who'd be in conformity with this trade.
