Lua library for generating a unique ID for OpenResty

# Description

This Lua library is a unique ID generator in OpenResty. 

You can use it to generate a unique ID that will not be duplicated for your OpenResty.

# The Unique ID pattern generated by this library

(13-bit millisecond-level timestamp)-(12-bit IP address)-(6-bit Nginx Worker PID)-(3 bit Nginx Worker number)-(6-bit auto-increasing random number)

E.g : ```1523881864432-010020100149-087846-000-005964```

# How to use

1. Perform initialization in ```init_by_lua``` or ```init_by_lua_file``` :

```lua

--Load Unique ID library and initialize

require("unique_id");

unique_id.init();

```

2. Use Unique ID library in your Lua script :

```lua

local id = unique_id.id();

```
