*Minimum* amount extracted/attracted per operation

Potentially helpful to have an upgrade which will switch the direction of the amount check.
This will primarily be useful for stopping machines with hybrid input getting blocked by less materials than they can complete a function with.

I would like this feature as well, but for a different reason - using Round Robin mode on an Attractor to send imbalanced inputs to multiple machines.

For example, an Inductor from Modern Industrialization takes 1 Steel Rod and 8 Copper Wires. If I run out of Copper wires in the input chest feeding multiple machines, one machine may receive fewer than 8 Copper Wires on its turn, and its remaining 1 wire (when available in the input chest) will go to the next machine -- therefore gunking up two machines. If I could make Round Robin wait for a minimum number of items, then this problem would be avoided.
