docs: Return an optional of an element from a specified position in an iterable. If the position is out of bounds
  an empty optional is returned. Positions start at 0.
  
  @param iterable the iterable
  @param position the position
  @param <E>      the type of the elements
  @return an optional from the given position, or empty if out of bounds
