Improve wave module error messages to include the offending value

Summary

The wave module currently raises errors without the offending value:

wave.Error: bad # of channels
wave.Error: bad sample width
wave.Error: bad frame rate

When values come from variables, configuration, or parsed data, the
traceback shows the call site but not the actual offending value. For
Wave_read, the values are parsed from the WAV file header and never
appear in the traceback at all.

Reproduction

import wave, io
wave.open(io.BytesIO(), 'wb').setframerate(-1)
# wave.Error: bad frame rate

After this change:

wave.Error: bad frame rate: -1

I have a patch ready and will open a PR shortly.

从 wave 模块的验证路径开始，包括 setframerate(-1)，以及 issue 中提到的 Wave_read 头部解析。重现当前错误，然后验证每条相关消息都包含引发错误的值，并确认 wave 的现有行为保持不变。
