Subject: feat: Expose readTree for downstream consumers

Exposes readTree from the package set but with a twist: It's exposed
as a functor that references the `.config` field from itself to get at
the configuration to be passed to packages.

This makes it possible for downstream users to make use of `readTree`
but with their own configuration.
