/**
 * Generic flat geometry data storage type
 * (an intermediate "Flat GeoJSON"
 * data format, which maps closely to the binary data buffers.
 * It is similar to GeoJSON, but rather than storing the coordinates
 * in multidimensional arrays, we have a 1D `data` with all the
 * coordinates, and then index into this using the `indices`
 * parameter
 *
 * Thus the indices member lets us look up the relevant range
 * from the data array.
 * The Multi* versions of the above types share the same data
 * structure, just with multiple elements in the indices array
 *
 * @example
 *
 * geometry: {
 *   type: 'Point', data: [1,2], indices: [0]
 * }
 * geometry: {
 *   type: 'LineString', data: [1,2,3,4,...], indices: [0]
 * }
 * geometry: {
 *   type: 'Polygon', data: [1,2,3,4,...], indices: [[0, 2]]
 * }
