[issue32056] bug in Lib/wave.py

[张德岳]

New submission from 张德岳 <abcdyzhang at 163.com>:

I found a bug in wave.py because there is no check for self._channel in _read_fmt_chunk function.
When I try to open a wav file which channel is zero, it will crash bacause of divided by zero in initfp function.
