Feature/11167: Addition of cost for each equipment in Shandalar

Addition of cost for each piece of equipment

• The Archipelago randomizer will also randomize equipment available for purchase in shops from the total pool available in the Shandalar world, instead of randomizing the prices of item's whose cost is missing, I instead added a cost to each of them that I think would be reasonable based on other items in the game and the item's power level.
