Main thread lag and skipped frames when mapboxNavigation.startTripSession() called

This issue occurs in our code, Ive provided a stripped down version of this issue on the following github link.

Android API: 21
Mapbox Navigation SDK version: 1.4.0
Code: https://github.com/JustinmClapperton/mapboxAndroidTest
Example: https://youtu.be/t0DjKnAMDN8

(You will need to add your own Mapbox API key to gradle.properties and strings.xml)

Steps to trigger behavior

1. Run the app
2. Try to drag the map around and watch for skips

Expected behavior

App performs smoothly with no lag on the main thread. LocationEngineRequest Params should be respected

Actual behavior

App performs incredibly slow with several skipped frames on the main thread. No matter what I set the following code snippet too updates still happen less than every second, this could likely be part of the lag I'm experiencing.

LocationEngineRequest request = new LocationEngineRequest.Builder(10000L)
                .setFastestInterval(5000L)
                .setDisplacement(1)
                .setPriority(LocationEngineRequest.PRIORITY_HIGH_ACCURACY)
                .build();

Inizia con la riproduzione mapboxAndroidTest collegata e aggiungi la API key richiesta in gradle.properties e strings.xml. Esegui l’app su Android API 21, chiama startTripSession(), trascina la mappa e confronta i log dei frame saltati con le impostazioni di LocationEngineRequest. L’attività è completata quando la mappa rimane reattiva e i parametri di aggiornamento della posizione richiesti vengono rispettati.
