Hello,

i'm testing your library right now to use it together with a fluentD stack and it looks like we could need an additional delimiter to the fired messages.

So would it be possible to configure an additional delimiter for the hook? For example a nullcharacter?
This could be easily done like this

func (f LogstashFormatter) Format(e *logrus.Entry) ([]byte, error) {
    ne := copyEntry(e, f.Fields)
    dataBytes, err := f.Formatter.Format(ne)
    releaseEntry(ne)
    dataBytes = append(dataBytes, []byte("\000")...)
    return dataBytes, err
}

What do you think about it?

Thanks
