Utilities in use by pro!.
These are kept separate from pro core utilities to allow for more dynamic inter-crate dependencies.
The main problem is that today Cargo manages crate features on a per-crate basis instead of
a per-crate-target basis thus making dependencies from pro_lang (or others) to pro_env or pro_storage impossible.
By introducing pro_primitives we have a way to share utility components between pro_env or pro_storage and
other parts of the framework, like pro_lang.
