cleanup: LogisticsNewPipeItemBoxRenderer takes an ItemIdentifierStack (#44)

For doRenderItem there is no need to convert first to an ItemStack
and then back to an ItemIdentifierStack on the hotpath if we can just
pass the ItemIdentifierStack directly.

This is a follow up to #40.

(cherry picked from commit 02af086)
