通过运行时修改authlib实现游戏外登录

#### 生成签名公钥
服务端返回的profile properties需要带有数字签名。
可以通过以下方法生成一个新的RSA私钥：
```
openssl genrsa -out key.pem 4096

然后从私钥产生公钥：
```
openssl rsa -in key.pem -pubout

生成方法见[签名密钥对](https://github.com/to2mbn/authlib-injector/wiki/%E7%AD%BE%E5%90%8D%E5%AF%86%E9%92%A5%E5%AF%B9)。

## 本项目与authlib-agent的关系
authlib-agent项目存在较多历史遗留问题，并且原项目的javaagent部分及后端部分耦合在一起，需要一起构建。因此将原项目的javaagent部分重写，并更名authlib-injector，同时提供更加友好的配置方式，以供其它yggdrasil服务端实现使用。
### 远程自动配置
对于实现了本规范中[扩展API](https://github.com/to2mbn/authlib-injector/wiki/Yggdrasil%E6%9C%8D%E5%8A%A1%E7%AB%AF%E6%8A%80%E6%9C%AF%E8%A7%84%E8%8C%83#%E6%89%A9%E5%B1%95api)的Yggdrasil服务端，可以直接通过添加以下JVM参数来配置，不需要配置文件：
```
-javaagent:{authlib-injector.jar的路径}=@{Yggdrasil服务端的URL（API Root）}

/**
* A JSONArray is an ordered sequence of values. Its external text form is a
* string wrapped in square brackets with commas separating the values. The
* internal form is an object having <code>get</code> and <code>opt</code>
* methods for accessing the values by index, and <code>put</code> methods for
* adding or replacing values. The values can be any of these types:
* <code>Boolean</code>, <code>JSONArray</code>, <code>JSONObject</code>,
* <code>Number</code>, <code>String</code>, or the
* <code>JSONObject.NULL object</code>.
* <p>
* The constructor can convert a JSON text into a Java object. The
* <code>toString</code> method converts to JSON text.
* <p>
* A <code>get</code> method returns a value if one can be found, and throws an
* exception if one cannot be found. An <code>opt</code> method returns a
* default value instead of throwing an exception, and so is useful for
* obtaining optional values.
* <p>
* The generic <code>get()</code> and <code>opt()</code> methods return an
* object which you can cast or query for type. There are also typed
* <code>get</code> and <code>opt</code> methods that do type checking and type
* coercion for you.
* <p>
* The texts produced by the <code>toString</code> methods strictly conform to
* JSON syntax rules. The constructors are more forgiving in the texts they will
* accept:
* <ul>
* <li>An extra <code>,</code>&nbsp;<small>(comma)</small> may appear just
* before the closing bracket.</li>
* <li>The <code>null</code> value will be inserted when there is <code>,</code>
* &nbsp;<small>(comma)</small> elision.</li>
* <li>Strings may be quoted with <code>'</code>&nbsp;<small>(single
* quote)</small>.</li>
* <li>Strings do not need to be quoted at all if they do not begin with a quote
* or single quote, and if they do not contain leading or trailing spaces, and
* if they do not contain any of these characters:
* <code>{ } [ ] / \ : , #</code> and if they do not look like numbers and if
* they are not the reserved words <code>true</code>, <code>false</code>, or
* <code>null</code>.</li>
* </ul>
