Feature Request: m3u8.MediaSegment implements fmt.Stringer

[keizo042]

hello dev.
Thanks you for your great work. the library is very useful :-)

I'd like to implement (m MediaSegment) String()string for testing like below.
When failing test, I'd like to report as m3u8 text.

package something

import (
	"github.com/grafov/m3u8"
	"testing"
)

func TestXXX(t *testing.T) {
	var expected, actual m3u8.MediaSegment

        actual = do_something()
	if expected.SeqId != actual.SeqId {
		t.Fatalf("expected:%s,  but actual:%s\n", expected.String(), actual.String())
	}
}

there are already (p *MediaPlaylist) String() string and it converts m3u8.MeidaSegment to string.
We can use the procedure to implement function I request.

If you agree to the issue but don't have enough time, I'd like to send PR.

This sounds reasonable, but there's a lot to output, what do you think it would show?

It would be good it is same result to media segment part of (p *m3u8.MediaPlaylist) String() string

When all m3u8.MediaSegment field is presense,
(p *m3u8.MediaPlaylist) Decode()(byte.Buffer, error) and (p *m3u8.MediaPlaylist) String() string dump like this .

#EXT-SCTE35:CUE="base64==",ID="identify",TIME=30
#EXT-X-KEY:METHOD=,URI="http://example.com/key",IV=iv
#EXT-X-DISCONTINUITY
#EXT-X-MAP:URI="http;//url",BYTERANGE=10@0
#EXT-X-BYTERANGE:10@0
#EXTINF:10.000,hogehoge
http://example.com/media.ts

I suppose it is not so a lot.

[bradleyfalzon]

That looks good to me.

@bradleyfalzon I think it is ok to implement such method. @keizo042 would you create PR?
