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
