Understanding of zlib protocol is baroque and wrong.

When pypng is doing zlib decoding it uses the unused_data attribute of the
decompressobj object.
This is wrong. As <a
href="http://www.python.org/doc/2.4.4/lib/module-zlib.html">the zlib
documentation</a> makes reasonably clear, this is only useful when there is
extra data past the
end of the compressed data stream.
The right thing to do is to use unconsumed_tail, but really that is only
required if we do incremental
decompressing (by limiting the output block size).
Consequently, the code needs to be much simpler.
