fix memory crash in prob_any_missing (#38)

The code fix addresses a memory crash issue in the `prob_any_missing` function. The fix includes adding a condition to check if `maxNumEvents` is less than `totalEvents`. If true, it fills the `probVec` vector with 1.0 and returns it. This prevents the memory crash and ensures proper execution of the function.
