Update our aerobulk-python code to output flux coefficients

[paigem]

Aerobulk allows for optional output of the drag/flux coefficients. We discussed updating aerobulk-python such that we can access the coefficients that are computed.

This will allow us to determine which terms in the flux equations contribute more to the small scale differences we observe: the nonlinearity in the coefficients or the nonlinearity in the equation itself (e.g. the product of winds and the difference in temperature).

@TomNicholas are you interested in helping with this code implementation?

This was based on discussions on Friday, Sep. 30th (notes here).

I think this would be a great thing to discuss more when/if we have a meeting with the aerobulk folks.
