The initial import of data from S/M and US/UM only included held items for Moon
and Ultra Sun. (Presumably those were the only games eevee had access to?)
I now have all four games and I've verified that the data file which
contains held items is completely identical between Sun and Moon, and between
Ultra Sun and Ultra Moon.
So we can just copy the held items from the other two games.
pokedex=> insert into pokemon_items (select pokemon_id, 27, item_id, rarity from pokemon_items where version_id=28);
INSERT 0 356
Time: 220.560 ms
pokedex=> insert into pokemon_items (select pokemon_id, 30, item_id, rarity from pokemon_items where version_id=29);
INSERT 0 362
Time: 102.063 ms
The only differences from Platinum are that Shuckle holds a Berry
Juice, Sky Shaymin holds a Lum Berry, and the *rizers are only held by
the final forms, only 5% of the time.
