Added additional 20 usec delay in hex_send_nybble to fix the program upload for the TI-74 which may be not as fast as the CC-40.
Done experimentally without deeper understanding of the hex-bus protocol, but it works without a single error since then on the TI-74.
Hope it does not damage the behavior when the CC-40 is connected.
