6d49d7b8f9 Implement zopfli compression, available as a CLI flag (-Z) 
Improves compression by about 10% over DEFLATE, but takes a very long
time at the moment, so it is off by default.

2573b20966 Add support for optimizing PNGs loaded in-memory. 
In keeping with being able to use oxipng as a library, this adds a way
for developers to optimize a PNG already in memory, instead of requiring
  it to exist on disk first.

85ea2c21e5 Remove FIXME sections from code 
One section can't be improved from what I can gather,
because we have to iterate the number of bits per pixel in advance.

The output section has been refactored to pull the block writing code
into a separate function.
