Devices that remain in queue for too long should be removed

[Ceiran]

This is to account for any devices that are permanently stationed near the pis that are sending out broadcast messages. These devices should be removed so that they don't clutter the data we collect and give faulty impressions of the population in a certain location.
A possible solution is to create a counter that keeps track of how many cycles it has been present in the queue for and set a constant value that serves as a threshold. If it exceeds the threshold, it should be removed.
