Similar to #96, we need to generate a polygon of the IEM domain to use for masking and cropping raster datasets. Basically this means applying some aggressive buffering (order 100 km) to capture all coastal nooks and crannies and outlying islands, and then spatially differencing this buffer along true "boundaries" with the original polygon
