Victron GX integration

To work, this needs

• https://github.com/freakent/dbus-mqtt-devices
• MQTT broker on the Victron controller to be active:

If you are not using the Home Assistant part (only MQTT), you must remove the api: line from your ESPHome configuration, otherwise the ESP will reboot every 15 minutes because no client connected to the native API.

I tested this on a Raspberry Pi with Venus OS, but I don't have a Victron setup (yet). The meter shows up like expected, but was not yet tested on a full ESS system:

I'll maybe add other configs later to add PV inverter data to a GX device via MQTT and Home Assistant.
