Added slow exit timer function: At the end of the dive the final ascent to surface should be done slowly. The new function provides a comparison of the current divers depth compared to a linear ascent simulated by the OSTC. The visualization is shown instead of the ascent speed with a little different appearance. The linear ascent is starting from the last stop depth and the time for the ascent may be configurated in the deco settings. The simulated and real peth is compared and the depth color changes based on the difference of the values. In case the diver is much below the timer depth then the timer will stop and wait for the diver to follow.
