这里提供了几种ID生成方法

类似mongodb的产生方式,零配置，ID有序,二进制占用12个bytes,字符串占用20个char

基于时间戳和自增序列的id生成器,类似于snowflake,vesta-id-generator,生成的ID是一个uint64的整数, 支持uint64,支持秒,毫秒两种模式,集群需要配置nodeId才能避免重复,毫秒模式需要注意时间回调会导致ID重复而报错 id粗略有序

shortid,生成的ID是字符串格式,无序并随机,不可以反解析,相比较teris-io/shortid,这里支持了base32,所有字段都参与随机参考: shortid go-shortid

要求生成的兑换码随机，无序，不易猜测，易输入，可逆可验证，兑换码中通常会包含一个ID信息
