Implement raster support for northern and southern projections #88

When a polygon is rasterized, it currently is done only in the web mercator projection. This is not ideal for areas close to the poles.

The client should support rasterizing the polygon in a polar projection, and then identifying that projection in the request so that the server code can process the raster image in that projection.

The ICESat2-SlideRule/sliderule#133 PR integrated GDAL into the server code and removed it from the client. By doing so, all regions are now passed as geojson objects when requesting raster subsetting support (even if they originate as shapefiles) and GDAL takes care of the projection using the projection supplied in the geojson (or shapefile). So this is now, in effect, fix.ed
