尝试 go 做一个简易版的 memory cache 实现

• REdis Serialization Protocol

In RESP, the first byte determines the data type:

• For Simple Strings, the first byte of the reply is "+"
• For Errors, the first byte of the reply is "-"
• For Integers, the first byte of the reply is ":"
• For Bulk Strings, the first byte of the reply is "$"
• For Arrays, the first byte of the reply is "*"

1. 实现 object, list, dict 基础数据结构
2. 实现事件循环 aeEventLoop
3. 参考 RESP 协议，实现流式读取&写入
4. 命令表实现 COMMAND，SET，GET
