Introduction of the split and support of the \032 separator.

This patch fixes #139.

Indeed, before this patch, we did not support the \032 separator.

To quote the RFC 6763:
   >  Note that nslookup escapes spaces as "\032" for display purposes, but
      a graphical DNS-SD browser should not.

Therefore, as of now, we will comply by replacing the given line with a
space before parsing it to our normal decoding workflow.
