Slot sequencing modes for filter-injectors
The filter-injectors used to always prefer to take items from the beginning of the source inventory. Because items also tend to get placed at the beginning of an inventory, this could lead to a chest+injector buffer only passing through a trickle of one type of item, where other item types are flowing in and getting later inventory slots. So now, the sequencing of source inventory slots is configurable, per-injector, by form. In addition to the old priority mode, there's now a random mode and a rotation mode. Incidentally refactor the filter-injector code, to avoid duplication between the itemwise and stackwise variants.
