Add bbox/id params & geometry method to @turf/helpers

[DenisCarriere]

Add bbox/id params & geometry method to @turf/helpers

• New - helpers.geometry method to help build Geometry from a string type & coordinates.
• Add bbox & id as parameters to all @turf/helpers Feature creation methods
  • helpers.feature
  • helpers.geometry
  • helpers.point
  • helpers.lineString
  • helpers.polygon
  • helpers.multiPoint
  • helpers.multiLineString
  • helpers.multiPolygon

helpers.geometry

 * Creates a GeoJSON {@link Geometry} from a Geometry string type & coordinates.

 * @returns {Geometry} a GeoJSON Geometry
 * @example
 * var type = 'Point';
