Simplifies modules so that a single Productivity 3 gets you 25% productivity and +400% speed. Beacons are removed and module slots are reduced to 1 in each machine.
Speed 3 is available (+400% speed) for recipes that don't allow productivity. Efficiency 1 gives -80% energy (but obviously can't be combined with the other two modules). Speed 1 and Productivity 1 exists only as a component for other recipes, other modules have been disabled.
The purpose of the mod is to remove the "beacon sandwich" layout that vanilla currently encourages. The values are chosen to be similar to beacon sandwiches but may end up being a bit weaker. Probably still too fast, particularly for green circuits.
