Add libdeflater as an option (#203) 
libdeflater is a Rust wrapper around
[libdeflate](https://github.com/ebiggers/libdeflate) - an alternative
heavily optimised library for deflate/zlib/gzip compression and
decompression that is intended for situations where upper bounds of the
output are well-known.

In my benchmarks on test files in the repo it has shown to be usually
both slightly faster and providing better compressed output than
cloudflare-zlib, but in some cases showing the opposite, so rather
than swapping defaults, it's currently provided as another option,
similarly to zopfli.

Since it's not strictly better in all cases, I'm not providing median
numbers, but you can check distribution histograms for time and size
differences here (all using `oxipng -o 6 -t 6 -P`):

659717cb1f Allow usage on wasm32-unknown-unknown target (#194) 
* Avoid using time API when we don't need it

This avoids a syscall to the time API when the result is ignored later anyway.

This allows to use the library with default options on wasm32-unknown-unknown, where the unimplemented syscall would panic otherwise.

* eval_send doesn't need to be an Option

We can drop the value manually, thus avoiding unwrap on each access.

* Keep single `use rayon::prelude::*`

If either `rayon` is already imported, then `rayon::prelude::*` should always resolve.

* Extract comparator

* Fully enable non-parallel mode

7460ffac73 Fix for passing in filenames that contain commas 
The versions of clap supported by oxipng default to allowing commas to be used as a delimiter for passing a series of values in a single physical command line argument, when parsing for a parameter that accepts multiple values. This prevents oxipng from accepting filenames containing commas (it splits them into segments separated by commas and treats each one as a separate path to a file to process, generally not finding any); this patch fixes this by disabling the delimiter behavior for the 'files' argument.

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.

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.

data attempts and calculate the best immediately during each thread.
