Read the data when the stream passed in is of type CArchiveStream

When the stream is of type CArchiveStream then Stat() is not implemented
and therefore it will not try to read the data.  Therefore if this is
not implemented then we try to read the data in chunks instead until
there is no more to read or it fails.
