+pycloudmusic 支持 proxy 时出现错误触发回调来更新 proxy
+
+```python
+from pycloudmusic import Music163Api, set_proxy, set_proxy_callback
+import asyncio
+
+# 正常这里是多个 proxy ip
+proxy = [
+    "http://117.114.149.66:55443"

+# 设置 proxy
+set_proxy(proxy[0])

+def proxy_callback(err):
+    # 如果 proxy 时出现错误这里更新
+    # 第一个返回值新的 proxy ip
+    # 第二个返回值 aiohttp.BasicAuth proxy 身份验证, 没有为 None
+    return proxy[0], None
+
+# 设置 proxy 更新回调
