Add an option to wake me up when caught up on sleep

For days when you don’t need to wake up by a specific time, it would be nice to have an option to wake you up when your sleep deficit is eliminated.

This could be used to prevent oversleeping, and thus feeling groggy because of it.

Currently, this can be (almost) achieved by setting a late alarm, and setting the smart wake up time to be very long, but it would be nice to have an option for this.
