Change log level from fine to info for unknown fields (#105)

This was already a suggested change in #75

It was my mistake to advise you to revert it back to fine. It would be better, if it was info instead.
Sorry, I was mixing up the meaning of FINE and DEBUG/TRACE and thought FINE would stand for lower severity, but in fact it stands for higher severity, which we do not want for this case.
