## 📝 依赖更新
### nac-acc-1410更新
在nac-acc-1410/src/error.rs中添加了From<String>实现：
```rust
impl From<String> for Acc1410Error {
fn from(msg: String) -> Self {
Self::InvalidGNACS(msg)
}
}
impl From<&str> for Acc1410Error {
fn from(msg: &str) -> Self {
Self::InvalidGNACS(msg.to_string())
}
}
```
这使得错误处理更加流畅。
