Add a side-by-side Python/R analysis as a tutorial

[alexishunzinger]

@battistowx and I have been working with JPL scientist, Jon Hobbs (@isujonhobbs), on notebooks that demo some analysis with the OCO-2 dataset. He is working on doing the access/analysis in both Python and R (in this repository: gesdisc-usecases/hobbs-oco-uncertainty-quantification).

We plan to display these side-by-side (or tabbed?) in the Cookbook to show Python and R users the analogous solutions for access and analysis.

Work is still in progress (follow progress in this repository).

Perhaps of interest to @ateucher, resident R enthusiast and Python user?

Excellent, thanks for tagging me! @cboettig will likely be interested too!
