Dongle loopback reports CRC as well as LQI of message

[rod-chapman]

I'm in section 3.9.1 of the beginner course. When I run radio-send.rs, the course book says I should see the LQI on the serial-term output from the loopback app running on the dongle. This is true, but I also get the CRC of the message, which is not expected. The book says I should see

received 5 bytes (LQI=49)

But what I actually get is

received 5 bytes (CRC=Ok(0xdad9), LQI=62)

Does the book need to be updated?
