torchaudio::io::StreamReader
============================

``StreamReader`` is the implementation used by Python equivalent and provides similar interface.
When working with custom I/O, such as in-memory data, ``StreamReaderCustomIO`` class can be used.

Both classes have the same methods defined, so their usages are the same.
