revset: added ascending attribute to addset class

In case both collections are in an ascending/descending order then we will be
able to iterate them lazily while keeping the order.

    If the ascending attribute is set, that means the two structures are
    ordered in either an ascending or descending way. Therefore, we can add
    them mantaining the order by iterating over both at the same time
