TurfMisc#nearestPointOnLine does not report distance along the route

Capturing from https://turfjs.org/docs/#nearestPointOnLine, the Feature returned from TurfMisc#nearestPointOnLine should return a location number property that describes the distance along the route of the computed intersection point, next to already available dist number property which describes the distance to the original point. Also would be great to explain those properties in the Javadoc and add public constant instead of relying on raw strings for dist and location.

Comienza en TurfMisc#nearestPointOnLine y compara el Feature devuelto con la documentación de nearestPointOnLine en turfjs.org/docs/. El trabajo estará terminado cuando el resultado incluya una propiedad de ubicación de distancia de ruta y las propiedades dist/location estén explicadas en Javadoc, reemplazando las cadenas sin procesar por constantes públicas.
