add_files support parquet files with field ids

### Feature Request / Improvement

I am using rust to commit to iceberg rest catalogue, however that requires field id's to be written for commit, however when I try to commit those same files using pyIceberg ( In case of re-initialisation ).
This error is shown
```
fb0b1e42-2c49-434c-b39a-da4586e7ef05-die_info.parquet because it has field IDs. `add_files` only supports addition of files without field_ids
```
If it is not assigned to someone I believe I can work on this.
Thanks!s

首先定位 add_files 入口點，並了解它目前如何處理帶有欄位 ID 的 Parquet 檔案。當 add_files 接受報告中描述的帶有欄位 ID 的檔案，同時保留對不帶欄位 ID 的檔案的現有支援時，工作就完成了。
