Can I read a MultiPolygon geojson with this library

Hi alex,

can I read a MultiPolygon geojson with this library?

import json
from shapely.geometry import mapping,shape
from shapely_geojson import FeatureCollection

way = """
{
   "features":[
      {
         "geometry":{
            "coordinates":[

The entire library is one short file: https://github.com/alekzvik/shapely-geojson/blob/master/shapely_geojson.py

The JSON representation is one-way: shapely -> JSON, not the other way around.

GeoJSON is very similar to the __geo_interface__ format that shapely does accept in shapely.geometry.shape(), though, so it shouldn't be too difficult: just convert the json to a dictionary and give it to that function.
