Is SPS30 self-cleaning running every so often?

Need to make this configurable and be sure it's setup to happen every so often (~once/week)!

Bumping to P0 because I'm certain the self-cleaning is not automatically happening, as I recently observed my sensor stop sending data even though the host RPi was running just fine. A restart of the sensor pipeline appears to have forced self-cleaning (I believe it runs automatically when the sensor is power-cycled: confirm this!) so I've hackingly added a weekly reboot to my unit to get around it for now. This really needs to be fixed properly ASAP.
