Feature request - Resource Store

[LeoDoesThings]

Is your feature request related to a problem? Please describe.
It would make the Skyblock experience more enjoyable if the crystals could be used as a currency and you could use them to buy items from a Skyblock Shop. This shop could also be used to get crystals by selling items from farming like cobblestone, seeds, wheat, etc.

Describe the solution you'd like
Implement a shop for blocks, food, spawn eggs, etc.

Additional context
I thought of this idea after trying out ASkyBlock on an older version of Minecraft where there is a mini-shop where you can buy resources. This concept could be expanded on by creating a fully-fledged in-game store for the players to buy resources they cannot get from farming like sand, dirt, armour, spawn eggs, etc.
