1. 遵循`RFC6749`规范，引入命名空间常量`RFC6749_ABNF_*`定义，从代码层面即可直观感受各`Providers`对规范的遵循度;
2. 在抽象`User`类，引入命名空间常量`ABNF_*`定义，直观感受对各厂商的授权信息抽象;
3. 在工厂抽象类中，引入命名空间常量`ABNF_*`定义，直观感受本LIB对`RFC6749`及厂商实现的抽象；
4. 调优`Psr\Http\Message\ResponseInterface::getBody()`获取返回值可能引发的流偏移而拿不到返回文本的潜在问题;
5. 使用相对路径的命名空间导入功能，对代码做了一点点修型;
6. 扔掉了下游包抛送的异常注释，代码注释仅专注于本LIB抛送的异常定义;
7. 支付宝&钉钉的`scope`拼接修型;
8. BC: 大小写`Exceptions\Feishu`调整为`Exceptions\FeiShu`;
9. BC: 部分抛送的异常调整为恰当类型;
