Update text-parasble PDF after the last few commits' changes

Make the resistor which is connected to the NPN's base and emitter 47k instead of 4.7k

Import netlist into Pcbnew layout software, spread out all footprints to prepare for placing components in their respective locations and begin routing

Make mpcie-outline footprint's back silkscreen pads graphic line rectangles to prevent errors in layout

Generate the netlist, next step is to import the netlist and corresponding footprints in Pcbnew

Assign placeholder footprints to WWAN antennae (identical to GNSS ones for now), add haptic motor schematic symbol and split up the connector and motor footprints, now ready to generate netlist and import it into Pcbew without errors

Add proper WWAN reset circuit using a MMBT2222A NPN BJT along with a 100nF cap and a TVS diode, make needed adjustements to the WWAN's SIM card circuit (UIM-CLK and UIM-RESET caps are NC & added 4.7k series resistor to SIM_DETECT_O#), assign the MMBT2222A footprint to KiCad's official SOT-23 footprint (identical to the spec sheet's recommended land pattern)

If necessary, the NC cap pads on UIM-CLK and UIM-RESET can be tested with various values during the first prototype debugging phase.

Make recommended changes after reviewer examined pages 13, 15-20

Add pull-up resistor to nCS pin of the NOR flash chip, make electrolytic caps tantalums again due to a the price difference not being significant
