[Asterisk-code-review] format wav: Read 16khz WAV samples properly (asterisk[13])

Change subject: format_wav: Read 16khz WAV samples properly
......................................................................

format_wav: Read 16khz WAV samples properly

When opening a file for reading, we aren't tracking the frequency of
the opened file, so we treat 16khz files as 8khz and do half reads.
