* Make SPI frequency configurable on Native * Make the tophone queue size configurable for Portduino * The modified SPISettings must be configured in setup(), after config.yaml is processed * make MeshService a pointer, so we can configure MAX_RX_TOPHONE at run time * Got a little over excited with refactoring * Silence a warning
