Conservative Region Aggregation with Xarray, Geopandas and Sparse

[allixender]

@benbovy @rabernat Hey, just tagging here. With @annefou and @tinaok we would be keen to explore that more systematically from the DGGS <-> unstructured grids side (and myself in general region aggregation over “raster” or “vector” data with DGGS anyway). Just pasting the link to my thread here where we hope to pick up the slack a bit Discrete Global Grid Systems (DGGS) use with Pangeo - #25 by allixender
