When adding a dive, make the final ascent slower
Simply trying to role-model safe behavior I guess. Fundamentally all this
should be configurable (so I added comments about that on the planner side
as well).
One of the interseting side effects of this implementation is that if the
user removes the safety stop and comes up directly from a deeper depth,
the slope of the ascent will change at 5m :-)
