Some memory-handling fixes

Free the correct bits of datum, not bits that have already been set to
NULL, after getting query results back (both in the command-line binary
and in the PD external).

In the external, free the results structure once the data has been
passed into the outlets.

\draw plot[domain=-2.4:2.4,samples=250] (\x, {0.15*sin(9.2*\x r)});
