Previously, I added a Dyeworks section that was incorrect: the base
item being available in the NC Mall does *not* mean you can necessarily
dye it with a potion!
In this change, we lean on Owls to tell us more about Dyeworks status,
and only group items in this section that Owls has marked as "Permanent
Dyeworks".
We don't have support for limited-time Dyeworks items yet—I've sent out
a message asking the Owls team for more info on what they do for those
items!
