Subject: Implement buffer reuse encoding.

This implements a buffer reuse mechanism in eris-encode. This is also a
backwards incompatible change, as the provided OUTPUT-FUNCTION now has an
additional argument and has to return an octet-vector buffer of equal size. This
is not yet implemented optimally, but should amount to a reduce of memory usage
and GC required, especially for larger files.
