Tag 96, is of type DATA, and it´s supposed to receive byte[] encoded (in our case) with FAST algorithm. So we have
to get a byte[] atn object to decode the FAST message. And it seems that quickfixN doens´t know how to parse
messages with byte[]. It tries to handle as a string but for obvious reasons doens´t work…

I think this is related to #41 and #97.
