Move libremanage to your path and add a configuration. See the USAGE which will
pop up if you make a mistake!

TODO
* in the config, most options should have defaults. for managers, host/port/username aren't really needed, ssh_config can take care of that.
* .libremanage.json should be toml or yaml so it can have comments
* there should be a state command which runs hidusb-relay-cmd state
