- The default slow speed value is `5` (`OAApplicationMode`) - Hopefully improves app usage in background

I was looking for a way to improve battery usage when trip recording while the app is in background.
This PR is a draft and builds on the following assumptions, please correct me if they are wrong.
In my understanding whenever the
distanceFiltervalue is reached, iOS will "wake" the app in the background. Currently when having a speed <10 this value defaults to 5 (meters?), which seems like a very high precision to me, especially when having bad GPS conditions. In my scenario it results in a 100% background activity every time (up to 1h background activity/hour), even when not moving the device at all.In my trip recording settings I've set the value for "Minimum displacement" to 50 meters/units. So there is no reason to call the update function every 5 meters/units, when no active navigation/following is running.
I was not able to test if this change has the expected impact, as I don't have a valid provisioning profile to install the app on my physical device. I however tested the changes in the simulator, to see if the values were set correctly.
What do you think, could this change possibly reduce power consumption when running in background or did I miss the point?
