Parse Face Areas from Inputted Datasets

[philipc2]

Proposed new feature or change:

If an inputted dataset already contains face areas, we should recognize and parse them, performing any unit conversions if necessary.

Do we store them in the face areas placeholder that we use when we compute internally or keep them in a new externally read face area? former might be the better approach, thoughts?

I think we should store them under the same variable for consistency. But we will still offer support for re-computing them if the user desires to use our functionality.
