Returns a pair of output/input ports to interact with the items of an inout array.

This function provides exclusive I/O access each of the inout port items, so only one of those operations can be performed at any given moment on any given item. For every item, when the value at its input is set to Some(_), the port is driven and its output is None. When the value at its input is set to None, the port is left in a high-impedance state and its output is the incoming value Some(_).
