Summary

Recreate Giselbaer's EMC Shop Locator mod, for finding the cheapest prices across shops

How to

https://github.com/gbl/EMCShopLocator
Parse what's on the sign and add it to a database, then look up that database whenever someone wants a specific item.

Additional feature possibility: select a shop and auto TP to it, or the possibility of a command (which can be implemented like this) to find a shop, e.g.: /finditem buy sand which will automatically teleport you to the residence of the shop that sells the cheapest sand, or /finditem sell netherite which will automatically teleport you to the residence of the shop that buys the most expensive netherite products (add in math here for ancient debris, netherite scrap, netherite ingots, netherite block)

Motivation

Useful mod from 1.12, port it to 1.16
