This is the first release under the new brand name

Highlights

1. HDFS reader plugin supports reading of binary data type
2. HDFS writer plugin supports writing of binary data type
3. Rewritten the implementation of ORC and PARQUET for more efficient execution
4. Rewrite the string type field splitting method using the database's own functions
5. Add support for auto guess splittable column (introduce new configure item autoPk)
6. Bump a dozen of 3rd dependencies to the updated version

该版本主要功能点

1. HDFS reader 插件支持读取 binary 数据类型
2. HDFS writer 插件支持写入 binary 数据类型，该数据可以从关系型数据库的 Blob 字段获取(Oracle 暂未支持）
3. 重写了 ORC 和 PARQUET 文件的读写代码，使用两个文件系统的直接API，提升读写效率
4. 重写了字符类型字段的分割函数，利用数据自身的功能提供了更合理的分割范围，而不是之前的随机字符串分割，并支持中文
5. 增加了读取关系型数据库表时自动猜测分割字段的功能（默认不启用），详见文档 说明
6. 大量第三方依赖包升级到最新版本
