cannot handle $BYTEORD= 1,2

For some FCS files I get the above error. I see it in the code here:

```
    if ('4,3,2,1' === this.text.$BYTEORD)
       isBE = true;
    else if ('1,2,3,4' === this.text.$BYTEORD)
        isBE = false;
    else
       throw 'cannot handle $BYTEORD= ' + this.text.$BYTEORD;
```

Any plans to fix this? Ill try myself
