The ResponseHeaders option does not work currently

[AnomalRoil]

Currently this does not print Response Headers in the logs:

	logger := httplog.NewLogger("http-relay", httplog.Options{
		JSON:     false,
		LogLevel: slog.LevelDebug,
		Concise: false,
		ResponseHeaders: true,
	})
	r.Use(httplog.RequestLogger(logger))

This is fixed by either #34 or #39 : the problem is that the Options are not being passed to the RequestLoggerEntry in the function NewLogEntry.
