Since there are still lots of scalar functions for which there is no bulk version, we should create a C implementation of mal.multiplex so that we can avoid the interpreter overhead of an iterator loop. In addition, we wouldn't break the dataflow.

The mal.manifold() has been added. It implements the multiplex over multiple aligned tables and a single output table.
