Sniffer + Colours + Flowers update

Sniffers are an ancient creature.

Minecraft has "ancient" old cloth colours like Ultramarine, Spring Green, Chartreuse, Magenta, Capri and Rose that don't exist in the game anymore.

> So adding new flowers for the Sniffer, where each flower would give the above "extinct dyes from old minecraft" is a perfect way to bring those old colours back. And also make the Sniffer more relevant as these Sniffer flowers can be the only way to obtain these rare colours.
