Adds a variant for the Adafruit Feather RP2040 RFM95, which pairs an RP2040 with an SX1276-based RFM95 module.

The RFM95 is wired to the RP2040's spi1 block, which this board's Arduino variant exposes as the default SPI object. Pin mapping is taken from the framework-arduinopico adafruit_feather_rfm variant: NSS=16, RST=17, DIO0=21, DIO1=22, SCK=14, MISO=8, MOSI=15.

TX power is capped at 20dBm as the RFM95 is PA_BOOST only.

Provides repeater and USB companion environments. BLE and WiFi companion environments are not included: the board has no wireless hardware other than the RFM95, and SerialBLEInterface/SerialWifiInterface are only implemented for esp32 and nrf52.

Credits to Matt Hixson for testing this.

I can confirm that the repeater firmware works on two Adafruit RP2040 LoRa boards.
