[Request] 派欧算力（PPIO）部分模型已经支持函数调用，希望能够支持

🥰 需求描述

派欧算力（PPIO）部分模型已经支持函数调用（例如dsv3，dsr1），希望能够支持

🧐 解决方案

与openai api调用一致，增加 search:fc

📝 补充信息

派欧算力接口接入 one-api 后，自定义 deploymentName 添加 search:fc 调用函数时遇到以下问题

• 以下接口 https://lobechat.example.com/webapi/chat/openai 响应被 unicode 编码。
• 函数调用结果中 arguments 参数首和尾各出现一个 {}。
• 接口 https://lobechat.example.com/webapi/plugin/gateway 因上述原因无法执行。

派欧算力接口与 one-api 接口通过 curl 调用，结果均正常：

其他尝试：

• 使用其他平台或接入 oneapi 的其他支持函数的模型，使用正常，可以正常调用函数
