`PerformanceWarning`

```
/home/appuser/.local/lib/python3.11/site-packages/webviz_subsurface/_models/parameter_model.py:156: PerformanceWarning:

DataFrame is highly fragmented.  This is usually the result of calling `frame.insert` many times, which has poor performance.  Consider joining all columns at once using pd.concat(axis=1) instead. To get a de-fragmented frame, use `newframe = frame.copy()`
