This module contains the code and queries for fetching data from the database,

It is intended to replace the functions in `gn3.db.traits` and `gn3.db.datasets`
modules with functions that fetch the data enmasse, rather than one at a time.

This module is part of the optimisation effort for the partial correlations.
