More inputs for Rubber Makers

Add more inputs (separate diesel, ethanol, and naphtha) for Rubber Makers to allow multiple rubber recipes to be used simultaneously.

@birdkilla2k1 [ideas] If you connect two pipes (e.g. Diesel and Naptha) right at any machine so the connector abuts it both are allowed into the machine allowing for two recipes to be used simultaeously. I am guessing you could add a third but never tried it

You can just use a balancer and feed a mixed pipe to the machine.
