 Returns a promise that yields a [GeoJSON feature collection](http://geojson.org/geojson-spec.html#feature-collection-objects) for specified shapefile *shp* and dBASE table file *dbf*. The meaning of the arguments is the same as [shapefile.open](#open). This is a convenience API for reading an entire shapefile in one go; use this method if you don’t mind putting the whole shapefile in memory. The yielded *collection* has a bbox property representing the bounding box of all records in this shapefile. The bounding box is specified as [*xmin*, *ymin*, *xmax*, *ymax*], where *x* and *y* represent longitude and latitude in spherical coordinates.
