PHP bindings for [libdeflate](https://github.com/ebiggers/libdeflate), a zlib replacement with significantly better performance.

## Features

At the time of writing, this extension only exposes libdeflate's compression APIs, since these are the simplest to implement.

Since libdeflate doesn't support stream decompression, the decompression APIs are less useful unless you know the decompressed size of the data before decompressing it.

## Performance

Compared to `zlib_encode()`, a 40% performance improvement can be observed at level 1, rising to 50-70% at level 6 (default), for approximately the same compression ratios. Also, `libdeflate_deflate_compress()` was observed to sometimes be faster at level 6 compression than `zlib_encode()` at level 1 compression.
