[FEATURE] Intelligent Elevator

[xCraimax]

Is your feature request related to a problem? Please describe.
Currently, the Lift has a "Queue", which isn't very smart.
Example:
I've got a Lift with 3 floors.
Person 1 on floor 1 calls it, enters it and selects floor 3.
But then person 2 on floor 2 calls the lift.
→ Now the Elevator firstly lifts itself up to floor 3 and then again down to floor 2, which isn't very effective.

Describe the solution you'd like
Example:
I've got a Lift with 3 floors.
Person 1 on floor 1 calls it, enters it and selects floor 3.
But then person 2 on floor 2 calls the lift.
Lift goes to floor 2, picks person 2 up. Person 2 now selects floor 1.
Now the Lift should go to floor 3, because floor 3 was picked prior to floor 1.

Describe alternatives you've considered
Not implementing it, because its too much.

Additional context
Would be very smart, for skyscrapers with 20+ floors.
