- [STABLE] When using the map operation for dataset objects and the parameters like: num_parallel_workers > 1 and python_multiprocessing=True, the multi-process mechanism is optimized, so that the data channel and child processes are mapped one by one, avoiding excessive file handle occupation, and closing_pool interface is also deleted.
- [STABLE] Add a batch of Vision, Text and Audio data augmentation operations.
- [STABLE] Fix a bug where the flat_map method of the Dataset class does not flatten the result.
- [STABLE] Unify import paths of dataset augmentation APIs to provide more easier way to use. Refer to [latest api usages](https://www.mindspore.cn/docs/en/master/api_python/mindspore.dataset.vision.html).

- [STABLE] 对于数据集对象使用map操作时同时num_parallel_workers>1并且python_multiprocessing=True时进行了多进程的机制优化使得数据通道与子进程一一映射避免了过多的文件句柄占用同时close_pool这个接口也被删除。
- [STABLE] 新增一批Vision、Text和Audio类数据增强操作。
- [STABLE] 修复数据集类的flat_map方法未将结果展平的错误。
- [STABLE] 统一数据集增强API的导入路径提供更简单的使用方法请参阅[最新的API用法](https://www.mindspore.cn/docs/zh-CN/master/api_python/mindspore.dataset.vision.html)。
