http-server http_compression = false invalid

Please answer these questions before submitting your issue. Thanks!

1. What did you do? If possible, provide a simple script for reproducing the error.

当我想强制不使用 compress 时，即便 header 内客户端提供了 Accept-Encoding ，因为我配置了 'http_compression' => false 都应该不执行压缩。这个在做微服务代理处理的时候我们需要关闭自动压缩。

<?php

function run($func)
{
    $scheduler = new \Swoole\Coroutine\Scheduler;
    $scheduler->set([
        'hook_flags' => SWOOLE_HOOK_ALL,
    ]);
    $scheduler->add(function () use ($func) {
        call_user_func($func);
    });
    $scheduler->start();
}

run(function(){
    $server = new \Swoole\Coroutine\Http\Server('0.0.0.0',9999);
    $server->set([
        'http_compression'    => false,
    ]);
    $server->handle('/', function ($requ, $resp) {
        $resp->end('hello');
    });
    go(function() use ($server) {
        $server->start();
    });
    $cli = new \Swoole\Coroutine\Http\Client('127.0.0.1', 9999);
    $cli->get('/');
    var_dump($cli->getHeaders());
});

array(6) {
  ["server"]=>
  string(18) "swoole-http-server"
  ["connection"]=>
  string(10) "keep-alive"
  ["content-type"]=>
  string(9) "text/html"
  ["date"]=>
  string(29) "Sun, 19 Apr 2020 15:02:20 GMT"
  ["content-length"]=>
  string(2) "25"
  ["content-encoding"]=>
  string(4) "gzip"
}

2. What did you expect to see?

3. What did you see instead?

4. What version of Swoole are you using (show your php --ri swoole)?
