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).

For better BoM generation, added placeholders for SOM, disṕlay, camera, WWAN card and wifi/BT card.
Datasheet links and supplier information can be stored in these new library symbols.

Add FDV301N footprint based on the manufacturer's given recommended land pattern, use lower ESR 220uF tantalum capacitors in place of previously selected ones, re-export the BoM

Double checked FET footprints to make sure those assigned to the official SOT-23 footprint are correct.

Assign u.FL to the coax connectors in the WLAN+BT circuit

Center the GNSS chip antenna on it's footprint design to make sure it's component coordinates are correct, add WLAN+BT placeholder footprint which is identical to the GNSS one (still needs to be selected)

The WWAN/BB chip antenna is likely going to be significantly different than the GNSS one (in terms of design and area) so it is not currently being used as a placeholder for it.

Create the NTB0104GU12 footprint based on the manufacturer's given recommended reflow soldering footprint and assign it to the respective symbols

Add BLM18PG121SN1D chip ferrite beads to the GNSS, proximity+ambient light sensor, and IMU +3.3V power pins

Use manufacturer's recommended land pattern for 74LVC1G32GW, NUP5120X6, and 74AUP2G08 (U1301, U1501, U1803), use more accurate VSSOP-8_2.4x2.1mm_Pitch0.5mm 3D model for 74LVC2G241 (U701), include SOT-563 3D model for NUP5120X6

Used manufacturer's given stencil/solder paste and solder mask dimensions whenever given. Some of KiCad's official footprints do not necessary align with the manufacturer's recommended footprints.

Add MIC2876 5V boost converter's footprint, assign it, assign it the DFN-8 3D model
