v1.0.0

• Feature: Change Compressor and Decompressor to use more efficient streaming compression context.
  (#28 by @clue)

  This also fixes any inconsistencies and supports proper error reporting for invalid data.
  Benchmark results suggest this improves both compression and decompression performance by ca. 25%.

• BC break: Require PHP 7+ with ext-zlib during installation and drop legacy PHP and legacy HHVM support.
  (#25, #26 and #28 by @clue)

  We're committed to providing a smooth upgrade path for legacy setups.
  If you need to support legacy PHP versions and legacy HHVM, you may want to
  check out the legacy v0.2.x release branch.
  This legacy release branch also provides an installation candidate that does not
  require ext-zlib during installation but uses runtime checks instead.
  In this case, you can install this project like this:

  $ composer require "clue/zlib-react:^1.0||^0.2.2"

• BC break: Remove deprecated APIs and mark ZlibFilterStream as internal only.

• Improve test suite by updating PHPUnit, clean up test suite and
  add .gitattributes to exclude dev files from exports.
