/**
 * Wrapper around Mapbox PBF representation of
 * a feature in a vector tile. It has the same semantics
 * as the original library (https://github.com/mapbox/vector-tile-js)
 * except that the features it contains expose their data
 * in a binary optimized format, rather than geoJSON.
 * The standard geoJSON types are preserved, but rather than
 * the geometry containing a `coordinates` (multi-dimensional) array
 * the spatial data is stored in a flat `data` array and then
 * referenced by indices in a separate `lines` array, e.g.
 *   geometry: {
 *     type: 'Point', data: [1,2], lines: [0]
 *   }
