Serial output format

The output from this sensor comes in packets of 4-bytes:

1. Data[0] = 0xFF: Packet Header
2. Data[1]= 0x0-0xFF: Data Most Significant Byte (MSB)
3. Data[2]= 0x0-0xFF: Data Least Significant Byte (LSB)

4. Data[3]= 0x0-0xFF: Data Checksum: = (0XFF + MSB + LSB) & 0xFF

5. Data is in MILLIMETERS

6. 16 bit value in mm = Data[1] << 8 | Data[2]
