refactor(print): 将 print 包重命名为 printer 并更新所有引用

将项目中的 print 包统一重命名为 printer，以避免与标准库或第三方库产生命名冲突。同时，
更新了所有相关模块对该包的引用，确保功能一致性和代码可维护性。

涉及文件包括：
- conf/new.go
- infra/service.go
- service/register.go
- service/service.go
- with/databases.go
- with/etcd.go
- with/memory.go
- with/redis.go

此外，删除了以下已废弃或未使用的代码文件：
- cmd/cmd.go
- data/map_float.go
- data/map_string.go
- oplog/new.go
- oplog/types.go
- print/print.go
- utils/ext.go
```
