Creating courses and/or lessons based on habitat type #50

It would be great if you could say something like "I want to learn all forest birds in my area" or "all sea birds in Europe". This could also be implemented as a branching, rather than linear, course structure, similar to what DuoLingo does: after finishing a chapter, you get to pick what you want for the next chapter.

But first we need habitat data for each species. There is some good information on how to do this here in the eBird best practices documentation: https://cornelllabofornithology.github.io/ebird-best-practices/covariates.html They use data from the MODIS satellite instrument, which has 500-meter resolution and is classified into 16 different land cover types. It's a bit involved to download this, but certainly doable.

NASA also has an easy to download single PNG, although at 0.1 degrees its resolution is probably a bit limiting: https://neo.sci.gsfc.nasa.gov/view.php?datasetId=MCD12C1_T1

Also MODIS data, may be the same, but at 0.05 degrees and there's a direct 1.2 GB download: https://lpdaac.usgs.gov/products/mcd12c1v006/

Downloaded the latter; preliminary docs are on the feature/habitats branch. Citation:

We'll also need to take https://en.wikipedia.org/wiki/Sinusoidal_projection into account on the vertical (latitude) axis.
