SPI.transfer() Test
SPI.transfer() is the main function of this library. In the past, we've used it to verify that data was sent properly
between various configurations. Now we want to test if it sends data as defined in the API. A byte should be sent to the
slave device, and a byte will be received as the return value from the slave device, as shown in Listing 13-11.
