Compared earthlib unmixing to national-scale remote sensing datasets generated by CSIRO covering Australia and Kenya. There was pretty good agreement between the photosynthetic vegetation and bare ground datasets, but less agreement with the non-photosynthetic vegetation fraction. OK then.

Also updated the MODIS default collection to use the nadir BRDF adjusted reflectance data (NBAR), and set shade_normalize=True as the default for unmixing routines.

Closes #9
