Hi, Jay.

The fix looks fine, but maybe we can to trigger added IIOException(remainingLen < 0) by the test?

> Issue : We have language tag length limit of 80 for iTXt chunk in PNGImageReader which is not spec compliant(http://www.libpng.org/pub/png/spec/1.2/PNG-Chunks.html#C.iTXt). There should not be limit on length of language tag.
