Filtering, jumpers, LEDs, misc
* Modified high level diagram to express the shared UART bus
* Renamed XCVR_VCC to XCVR_13V8
* Add solder jumpers on audio, PTT and UART lines for easy prototyping/bypassing
* Added bypass caps on XCVR side data and audio connectors
* Add series ferite beads on data ICs Vcc
* Added schottky diodes to all XCVR_13V8
* Changed series resistors of RXLED/TXLED/VccLED for 6mA current
* Added power LEDs on XCVR_13V8 connector terminals
* Added power LED for XCVR_5V rail
