Enchantment data is stored in items like so:
{id:level,id:level}
This is difficult to work with. This outputs a copy formatted as [{id:<name>,level:<value>},{id:<name>,level:<value>}] for easy enchantment manipulation.

ie;
{"minecraft:sharpness":5,"minecraft:looting":2}
converts to
[{"id":"minecraft:sharpness","level":5},{"id":"minecraft:looting","level":2}]

USAGE:

1. in storage, set xzu:temp in to your enchantment map.
2. run function xzu:enchant/build_enchantment_map/main
3. your formatted map is located in xzu:temp out

Example:

# put enchantments from players held item in storage input
data modify storage xzu:temp in set from entity @p SelectedItem.components."minecraft:enchantments"

# convert map
function xzu:enchant/build_enchantment_map/main

# see formatted data
data get storage xzu:temp out

NOTE:
This requires 0 0 to be chunkloaded, and will set 0 0 0 to be air. XZUtils handles this automatically, but there will be an air block at 0 0 0 every time this function is used.
