At some point the code around this changed, I believe this used to reduce over
file ids. However today it reduces over entire library maps, so it passes a map
instead of an id to `dm/get-in files`. This then hashes the library which
forces it to decode all of its shapes, and then it fails to lookup the data. So
the component/colors/typography counts were always returning 0.
Using reduce-kv fixes this, and we can just get the library data directly with
`(:data library)`.
