Some ECUs require messages to be padded to full length (typically 8 bytes), even though the actual payload within the message may be shorter. When performing manual testing against such targets, the user needs to add a bunch of .00 data bytes after the payload to pad the message to the correct length.
It would be nice to have an optional argument which enables automatic padding, so that e.g.
./cc.py send message -pad 0x123#67.89
would automatically be padded to correspond to
./cc.py send message 0x123#67.89.00.00.00.00.00.00
in order to simplify such use cases.
