[issue32056] Improve exceptions in aifc, sunau and wave

[Serhiy Storchaka]

PR 5951 adds explicit checks for the number of channels and sample width when read audio files in aifc, sunau and wave and converts some struct.error to EOFError when the file is truncated in wave.

This change can break an existing code that currently successfully opens corrupted audio files and read only headers, but not audio samples. Therefore it is safer to not backport it, even if classify this issue as a bug.
