Functions
int	sht1x_init (sht1x_dev_t dev, const sht1x_params_t params)
	Initialize the SHT10/11/15 sensor.

int16_t	sht1x_temperature (const sht1x_dev_t *dev, uint16_t raw)
	Calculate the temperature from the raw input.

int16_t	sht1x_humidity (const sht1x_dev_t *dev, uint16_t raw, int16_t temp)
	Calculate the relative humidity from the raw input.

int	sht1x_read (const sht1x_dev_t dev, int16_t temp, int16_t *hum)
	Read the current temperature.

int	sht1x_configure (sht1x_dev_t *dev, sht1x_conf_t conf)
	Apply the given configuration (= status byte) to.

int	sht1x_read_status (sht1x_dev_t dev, uint8_t status)
	Read the status byte of an SHT1X sensor.

int	sht1x_reset (sht1x_dev_t *dev)
	Reset the sensor's configuration to default values.
