More compressor for elton compress middleware.

- `SnappyCompressor` Snappy compression algorithm is fast, but not aim for maximum compression. It's useful for Intranet. Not support compress level.

- `ZstdCompressor` Zstandard is a real-time compression algorithm, providing high compression ratios. Compress level is 1-2, default 0(2).

- `Lz4Compressor` LZ4 is lossless compression algorithm, providing compression speed > 500 MB/s per core, scalable with multi-cores CPU. Compress level higher is better, use 0 for fastest compression.

```go

package main

import (

	"bytes"

	"io/ioutil"

	"net/http"

	"github.com/vicanso/elton"

	compress "github.com/vicanso/elton-compress"

	"github.com/vicanso/elton/middleware"

)

func main() {

	e := elton.New()

	// 需要注意添加的顺序，压缩是按添加的选择顺序选择适合的压缩方式

	// 此处只是示例所有的压缩器，正常使用时，按需使用1，2个压缩方式则可

	config := middleware.NewCompressConfig(

		&middleware.BrCompressor{

			MinLength: 1024,

		},

		new(middleware.GzipCompressor),

		new(compress.SnappyCompressor),

		new(compress.ZstdCompressor),

		new(compress.S2Compressor),

		&compress.Lz4Compressor{

			MinLength: 10 * 1024,

		},

	)

	e.Use(middleware.NewCompress(config))

	e.GET("/", func(c *elton.Context) (err error) {

		resp, err := http.Get("https://code.jquery.com/jquery-3.4.1.min.js")

		if err != nil {

			return

		}

		defer resp.Body.Close()

		buf, err := ioutil.ReadAll(resp.Body)

		if err != nil {

			return

		}

		c.SetContentTypeByExt(".js")

		c.BodyBuffer = bytes.NewBuffer(buf)

		return

	})

	err := e.ListenAndServe(":3000")

	if err != nil {

		panic(err)

	}

}
