Describe

This PR does the following-

1. Adds missing imports for paddlespeech/s2t/io/reader.py and paddlespeech/audio/transform/perturb.py file.
2. Fixes an implementation of a special method (__len__) for SoundHDF5File class.

Our bug fixing tool generated the following message-

In file: reader.py, class: SoundHDF5File, there is a special method len that contains an unexpected number of parameters. Each call to this method will result in a TypeError. iCR suggested that special methods should have an expected number of parameters. More infomation can be found in the Python documentation on the various special method.
