This is in progress for 1.18.

• fix chest monitor
• Fix memory cards with generalized inventory and remove special casing for fluids
• Remove AppEngInternalAEInventory, move cell workbench over to generalstackinv
• Remove fake "type only" slots (not needed with new config inventories in type mode)
• Remove IAEFluidInventory, IConfigurableFluidInventory, IAETank et al
• Remove FluidSlotPacket
• Try removing GenericStackSyncHelper and move to wrapped GenericStacks and normal slots
• Remove AEStack, IAEStack, AEItemStack, AEFluidStack, et al.
• Remove IAEItemList and all related classes
• Introduce immutable replacement (GenericStack)
• Make GenericStack unwrappable/wrappable into an ItemStack (replaces FluidDummyItem/WrappedFluidStack)
• Implement rendering for a wrapped GenericStack in such a way that it delegates to AEStackRendering
• Move all filter and config inventories to use Set<AEKey> where possible (KeyCounter where not, potentially implement KeySet as a Set alternative with fuzzy match support)
• Investigate why PatternTermSlot has custom click behavior when CraftingTermSlot already seems to implement the same behavior?
