    examples: nrf24l01_term: reserve RX terminator
    
    read_pkt() terminates the received payload with buff[ret], but a full-size 
read can leave no room for that trailing NUL byte.
    
    Limit the read length to one byte less than the buffer size so the received 
payload remains safely terminated before it is printed.
