Request: add a command to dump udev config to stdout

[ali1234]

It is tricky to run a script installed by pip --user as root because sudo changes the environment. This problem would be mitigated if I could do something like:

rivalcfg --dump-udev | sudo tee /etc/udev/rules.d/99-steelseries.rules && sudo udevadm control --reload

You are right... and this can probably be useful for packagers too... :)
