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.

Comece em TurfMisc#nearestPointOnLine e compare o Feature retornado com a documentação de nearestPointOnLine em turfjs.org/docs/. O trabalho estará concluído quando o resultado incluir uma propriedade de localização da distância da rota e as propriedades dist/location forem explicadas em Javadoc, com constantes públicas substituindo strings brutas.
