Cyroner expects candump log files, not candump stdout. To generate output in the correct format, invoke candump with `-l` or `-L`. For more info see [pycyphal.transport.can.media.candump package — PyCyphal 1.20.0 documentation](https://pycyphal.readthedocs.io/en/stable/api/pycyphal.transport.can.media.candump.html)
