Correct aoc values in case a run stopped before the budget was exhausted

Args:: ioh_function: The function in its final state (before resetting!) logger: The logger in its final state, so we can ensure the settings for aoc calculation match budget: The intended maximum budget
Returns:: float: The normalized aoc of the run, corrected for stopped runs
