      Added additional XOR gate to the WWAN page. This makes it possible that the polarity of the SIM_DETECT signal is configurable by one single O-Ohm-resistor.
      This adds more flexibility concerning modem choice, as there are both polarities of this signal used by different modem manufacturers.
      Added placeholder symbol for modem card (which holds now datasheet/bom information). The MPCIE socket has datasheet information, too.
      Picked two electrolytic capacitors (220uF/10V) by Panasonic by distributor TME.

      Replace WWAN M.2 circuit with one intended for mPCIe modules, include 74LVC1G08 single 2-input AND gate, create the AND gate's footprint and use the official SOT-23-5 3D model
      
      The mini-SIM slot will need to be replaced with one that has an active-LOW detection pin. Will want to see if we can find cheap electrolytic to replace a few of the tantalum caps with (not all since we still need some low ESR, high capacitance, low profile, caps).
