Feature Request: Specify Thresholds as Stacks

[Gullyn]

Thank you so very much for implementing this feature! I'm starting to use stack thresholds and so far haven't come across any issues.

I have come across one: Space Science Pack, insane amounts of those are required to trigger stack threshold

I like the idea of stack thresholds. But can you confirm that setting a stack threshold will be used for items and the normal threshold for fluids if both are set? If so then good work. Finally one can provide both items and fluids from one station. Till now I always had to provide items and request fluids or vice versa.

They work as outlined by me before:
- When a stack threshold signal is set items will use that regardless of old stack signals set
- Fluids still only use the old threshold signals
