Example of use

    import "github.com/go-dev-frame/sponge/pkg/logger"

    // (1) used directly, it will be initialised by default
    logger.Info("this is info")
    logger.Warn("this is warn", logger.String("foo","bar"), logger.Int("size",10), logger.Any("obj",obj))
    logger.Error("this is error", logger.Err(err), logger.String("foo","bar"))

    // (2) Initialize and then use
    logger.Init(
        logger.WithLevel("info"),     // set the data logging level, the default is debug
        logger.WithFormat("json"),  // set output format, default console
        logger.WithSave(true,         // set whether to save the log locally, default false
        //    logger.WithFileName("my.log"),      // file name, default is "out.log"
        //    logger.WithFileMaxSize(5),              // maximum file size (MB), default 10
       //     logger.WithFileMaxBackups(5),        // maximum number of old files, default 100
       //     logger.WithFileMaxAge(10),             // maximum number of days for old documents, default 30
       //     logger.WithFileIsCompression(true), // whether to compress and archive old files, default false
        )
    )
    logger.Info("this is info")
    logger.Warn("this is warn", logger.String("foo","bar"), logger.Int("size",10), logger.Any("obj",obj))
    logger.Error("this is error", logger.Err(err), logger.String("foo","bar"))

// (3) with hooks
    logger.Init(
        logger.WithLevel("info"),
        logger.WithHooks(func(entry zapcore.Entry) error {
            if strings.Contains(entry.Message, "error") {
                fmt.Println("it contains error message")
            }
            return nil
        }),
    )
    logger.Error("this is error", logger.Err(err), logger.String("foo","bar"))
