 * RADIOLIB_DEFAULT_SPI - default SPIClass instance to use.
 * RADIOLIB_NONVOLATILE - macro to place variable into program storage (usually Flash).
 * RADIOLIB_NONVOLATILE_READ_BYTE - function/macro to read variables saved in program storage (usually Flash).
 * RADIOLIB_TYPE_ALIAS - construct to create an alias for a type, usually vai the `using` keyword.
 * RADIOLIB_TONE_UNSUPPORTED - some platforms do not have tone()/noTone(), which is required for AFSK.
 * RADIOLIB_BUILTIN_MODULE - some platforms have a builtin radio module on fixed pins, this macro is used to specify that pinout.
 *
 * In addition, some platforms may require RadioLib to disable specific drivers (such as ESP8266).
 *
 * Users may also specify their own configuration by uncommenting the RADIOLIB_CUSTOM_ARDUINO,
