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

08eb44ec1a Partially implement --preserve 
Needs better implementation once stable Rust improves,
or perhaps see if there's a crate for this

Reference #4 but keep open

f3b8665278 Use miniz for compression strategies 0 and 1 
Worst case (RGB/A images) it performs similarly to zlib
Best case (Indexed images) it performs 1-2 orders of magnitude better

Zlib is kept for strategies 2 and 3, where it performs an order of
magnitude better than miniz

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.

Fixes #19

132a15403a Don't store intermediate copies of compressed image data unless it is current best.

87e21c2020 Limit number of simultaneous threads to help memory usage at high opt levels 
Still uses a lot of memory. Would like to remove the storage of all compression
data attempts and calculate the best immediately during each thread.
