b Newly built requesters don't come first in round robin order

If you have:
- a requester station requesting 100K lubricant with a threshold of 25K
- a provider station offering 20K lubricant
then as expected no delivery is created yet.

If you then construct a new requester station requesting 10K lubricant with a threshold of 2K, then no delivery is created either. Increasing the priority of the new station to 1 causes the delivery to happen immediately.

I understand that requesters of equal priority are prioritised according to least-recently-delivered-to to get round-robin behaviour per the mod description and I agree that is desirable, but should a newly created station be considered least-recent (since it's never had a delivery at all?)

I'm not sure whether I consider this a bug or not but it was surprising and caused me some lengthy debugging to try to work out why a delivery wasn't occurring as I overlooked the existing station requesting a larger, currently-unsatisfiable amount, so it might be worth changing?

Hm, after experimenting with this a bit more it looks like the behaviour might be a bit different than I assumed from the description.

Is the actual behaviour that there's basically just a queue of requesters that are waiting for a given resource, and whenever they get a delivery they go to the back of the queue if they still need more?

If so then that totally explains the behaviour of a newly-built station; it's just not how I interpreted "the least recently used requester station will be prioritized". Maybe it would be clearer to say "the requester station that has been waiting the longest will be prioritized"?
