Remote command execution on host from CMM2

REXEC allows you to remotely execute commands on an attached host machine from the CMM2 command line. It uses server on host (Python3 needed) and Xmodem for data transfer (correct for filesize, so you don't end up with those pesky trailing bytes at the end of a transfered file).
