  --polarity            SPI polarity. Default: False
  --cs-high             SPI chip select active level. Default: False
  --lsb-first           SPI bit order. Default: False
  --three-wire          SPI 3-wire mode. Default: False
  --loop                SPI loopback mode. Default: False

$ spi-repl --speed 5000000
SPI device: /dev/spidev0.0 speed: 5000000 bits_per_word: 8
now enter hex strings to send to the device
/dev/spidev0.0 <<< 0100
/dev/spidev0.0 >>> 0008
/dev/spidev0.0 <<< 010000000000000000000000000
expected hex string ('00112233445566778899aabbccddeeff')
