[FEATURE] Rotatable stacking machines

[KubeRoot]

Name of feature: Rotatable stacking machines

Additional Info:

Add the ability to change the input and output sides of stacking machines.
Stacking machines are a standard part of disposals systems, but there is currently no way to change their direction, forcing the players to build convoluted conveyors that pass on a certain side of a stacking machine.
This rotation could be implemented via the stacking console, alt-click, a context menu entry, or any of the tools, since the stacking machine does not interact with any of those things at the moment.
Additionally, the rotation could be either independent, allowing for more (perhaps too much) flexibility, or have the output locked to the opposite side of the input.
