title: Import mssql spatial fields into geopandas/shapely geometry
body: <p>I cannot seem to be able to directly import mssql spatial fields into geopandas. I can import normal mssql tables into pandas with Pymssql without problems, but I cannot figure out a way to import the spatial fields into shapely geometry. I know that the OGR driver for mssql should be able to handle it, but I'm not skilled enough in sql to figure this out.
  This is more of an issue for lines and polygons as points can be converted to x and y coordinates from the mssql field.
  Thanks!</p>
