Resolve "Change NMDBDataAttacher to not require a CRNSDataHub"

Description

The NMDBDataAttacher currently takes as a argument the CRNSDataHub. Change this so it simply takes a dataframe. This makes it more flexible and we can adjust the CRNSDataHub to use it internally on the attached DataFrame in the Hub.
