Capture Differential Signals

Allow to connect two probes to a differential pair (RS485, CAN, LVDS) and combine in hardware the signals to generate a single data stream.
It would be useful to have invalid or idle states being recorded along with the digital data.
Also the polarity and threshold should be configurable.

    This seems like a requirement given how many protocols seem to be migrating to differential signaling. Many of them seem like they are out of the frequency range of smaller analyzers like this so maybe that matters a little less. RS485 and CAN are the most common differential ones I see... Many devices are so small now that output/line level is the best and least damaging way to sample the signals. Since the Logic series can support > 5V now, this seems a worthy addition.

    We're definitely keeping this in mind for future hardware generations, as well as possible accessories. The current hardware generation couldn't do this properly though.

    ... even 10 baseT signals could be looked at.
