====== minecraft:single_enchantment ======
Enchants the given item stack with a specified enchantment and randomly picked level for that enchantment that is then clamped between 1 and the enchantment's maximum level.
It also increments the wanted item stack at the specified index with the picked level using the following calculation, where ''picked_level'' is the picked level and the other parameters are used from the fields in the trade modifier:
  random_integer(base_random_cost + picked_level * per_level_random_cost) + picked_level * per_level_cost
If the picked enchantment is a treasure enchantment, the added count is multiplied by 2.
