Hoymiles inverters allow setting relative limits with a precision of 0.1 %. this changeset allows to utilize this precision. * preserve accuracy when decoding power limit * Web API: process floating point limits * MQTT: process floating point limits * use appropriate accuracy for limits in web UI * HASS: step for relative inverter limit is 0.1 %
