Connect Same Name Input Signals

[Raffzahn]

Ist:

Input signals with similar names are not connected: Example:

{ assign:
 ["out",
    ["OR",
      ["AND",  ["INV", "a"], "b"],
      ["NAND", ["INV", "b"], "a"]
    ]
  ]
}

Soll:

When possible, input signals with same names should be connected.

Basicly this requires extending the schematic to the left by one step for each signal.

This would go well with implementing the extended input signals wavedrom/wavedrom#92

Another issue would be implementing feedback signals (seperate issue to come)
