CRCs doesn't match

[efimovalex]

Code:

const i2CAddress = 0x5c
const i2CBus = 1

// Server struct
type Server struct {
	Sensor *aosong.Sensor
	I2C    *i2c.I2C
}
func main() {
        var err error
	s := Server{Sensor: aosong.NewSensor(aosong.AM2320)}
	s.I2C, err = i2c.NewI2C(i2CAddress, i2CBus)
	if err != nil {
		log.Printf(err.Error())
	}
	fmt.Println(s.Sensor.ReadRelativeHumidityAndTemperature(s.I2C))
	defer s.I2C.Close()
}

Debug info:

CRCs doesn't match: CRC from sensor(0) != calculated CRC(6912)

Any ideea why the CRC from sensor is 0?
I am able to read the sensor on the same bus with the same address with a python script.

Found the issue, the function ReadRelativeHumidityAndTemperatureMult10 for AM2320 makes reads twice, submitted a PR with the changes that fixes this issue.
