tools/pyboard.py: Add option --no-follow to detach after sending script.

Browse Source 
This option makes pyboard.py exit as soon as the script/command is
successfully sent to the device, ie it does not wait for any output.  This
can help to avoid hangs if the board is being rebooted with --comman (for
example).

Example usage:

    $ python3 ./tools/pyboard.py --device /dev/ttyUSB0 --no-follow \
        --command 'import machine; machine.reset()'
