Implement faster Aggresive Similar Stockpile Limit check algorithm

[ubergarm]

Instead of iterating over all pawns and checking current jobs, grab the private ReservationManager.reservations List<ReservationManager.Reservation> and iterate over all hauling jobs.

Test this on a large colony to make sure it isn't too CPU intensive.

Initial testing shows that iterating over all reservations is much more performant and provides better results (as vanilla algo's seem to queue up and reserve two hauling jobs at a time so this let's a pawn haul for a longer period of uninterrupted time so less overhead shuffling jobs)
