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.

aaf443fca7 Similarly optimize unfilter mode 2 
Unfilter mode 1 can't benefit from this optimization
because it modifies and reads from the same line of data

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.
