Explore returning units

[chriscarrollsmith]

The old v2.0 API returned a unit multiplier with the observation value so you knew whether you were dealing with, e.g., millions or billions.

Currently, our returned dataframes do not include this. Presumably this information is available from the 3.0 API somewhere. Let's figure out where, and include it!

RIMF-25

Update: unit_multiplier is not needed with the new API because numbers are returned with the multiplier already applied!

However, there is information about units in the returned API response from the data/dataflow endpoint. Under data.structures[0].attributes.dimensionGroup: 1. There's an attribute with id: "UNIT". 2. It has a values array containing, e.g., [{"id":"PT"}, {"id":"XDC"}]. These indicate that the units used in the data can be "PT" (Percentage) and "XDC" (Local currency). Perhaps we want to return this with our dataframe.
