Py3: can't print record with raw fields

[Wooble]

pymarc.field.Field.__str__() uses native str as the arguments to self.data.replace, but in a RawField, data is a bytes object, so we get TypeError: 'str' does not support the buffer interface

RawField should probably have its own implementation of __str__, although it's unclear to me how we should represent a field with an unknown encoding as text...

Is this issue resolved?

[Wooble]

It's not, and looking deeper into it I can't see a good way to represent an arbitrary byte in MarcBreaker (http://www.loc.gov/marc/makrbrkr.html#mechanics) format especially since "" means "space" in the 00x fields, so "\x" doesn't work. Of course, these fields should be all ASCII, but the whole point of RawField is that sometimes they're not in the real world.

I suppose I could see how MarcEdit treats such a pathological record.
