TurfMeasurement#length method cannot handle empty lists

The other day, I encountered what I regard as an issue in the following Code snippet: https://github.com/mapbox/mapbox-java/blob/4ae8b78746fb37b2673364bdd4c8702057f3e7f3/services-turf/src/main/java/com/mapbox/turf/TurfMeasurement.java#L227
The scenario is the following: We have a list of GPS points of which some or all are invalid which is denoted by the coordinates being (0 , 0) - which IS bad Design, but our Team cannot change this... 🙄. Thus, we filter out those points before passing it to the length method. We just encountered an IndexOutOfBoundsException when the list is empty because there is no length check on the list. I guess the fix here is relatively easy, but the question ist - what should be returned in this case. We built in a check before hand returning 0 in this particular case. Maybe even a checked exception might be a feasible idea.

Comienza en services-turf/src/main/java/com/mapbox/turf/TurfMeasurement.java, cerca del método length enlazado, y reproduce el fallo con una lista vacía. Comprueba cómo gestiona el método las listas normales de puntos y revisa los usos cercanos para establecer el contrato previsto para entradas vacías. Se considera terminado cuando el comportamiento está acordado, el caso de lista vacía ya no produce una excepción inesperada y la cobertura de regresión lo verifica.
