Write data to i2cdev object at a given registry position using optional precision for the data byte used for the data.
dev - connected i2c device opened using i2cdev
reg - registry position to write to.
datain - data to write to device. Datasize should not exceed the constraints of the data type specified for the precision.
precision - Optional precision for the input write data. Currently known precision values are uint8 (default), int8, uint16, int16
