Wandering trader trades based on superflat/skyblock

The trades from wandering traders should be based on blocks that are unavailable in worlds like skyblock or superflat. Not just for those worlds, but in general would help. The trader is meant to sell exotic goods that might now be in your area, and anything that can be grown from nothing (or close to nothing) shouldnt count. The only trade I would suggest removing based on this is gunpowder. As for new trades: Granite, diorite, andesite, calcite, tuff, deepslate, netherack, blackstone. Red sand, mycelium, snow, nylium. Lava bucket. Amethyst crystals. Sponges, prismarine, heart of the sea. Suspicious gravel/sand (or individually: sniffer eggs, pottery sherds, the music disc, the templates) Some Music discs, templates... and technically ancient debris and block forms of ores should be added but they probably shouldn't be.
