Balances the left and the right side of a transport belt by taking items alternately left and right from the input belt. If one side is empty it will be skipped. Output goes the same: one left and one right, if one side is blocked it will be skipped.

Known Issues:
-Transport belts are getting rendered above the splitter

Known Limitation:
-Before and after the splitter there must be a straight transport belt
