Off be one error in getSerialNumber

[ogni4247]

In getSerial number, there is an off by one error when terminating the string:
{
// request from SCD30
if (ReadFromSCD30(CMD_READ_SERIALNBR, (uint8_t *) val, SCD30_SERIAL_NUM_WORDS * 2) != SCD30_SERIAL_NUM_WORDS * 2) return(false);
val[(SCD30_SERIAL_NUM_WORDS * 2) + 1] = 0x0; // terminate
return(true);
}

It should be:
val[(SCD30_SERIAL_NUM_WORDS * 2)] = 0x0; // terminate
