Fail decode if continuing to get insufficient size error
In the case that the low level LZW decoder has indicated insufficient destination size, if another call to decode returns this status after adjusting the destination size, consider it an error. Subsequent iterations will not return a larger destination size, since the expected row size doesn't change, so the code will just loop infinitely, trying to decode a too large row.
