Only loading the DEM with rasterio and then plotting with EarthPy.

I did a little cheating in QGIS/GDAL though, where I “reprojected” (to give it a working projection for Earth’s geospatial tools) and downsampled it to 1km grid resolution, because my Jupyter notebook would run out of memory when doing the hillshading and plotting together. I got a funny message in QGIS that informed me that the on-the-fly reprojection doesn’t work, because WGS84 and MARS are not the same celestial bodies :-D Aww, sweet.
