aider: Modified show_stats function to plot a bar graph with the average of "pass_rate_1" for each "edit_format" within each model, grouping the bars for each model together.

# Context:
USER: don't combine the edit formats. plot a different bar for each model/edit_format combo. But group the bars for each model together.
ASSISTANT: To implement this change, we need to modify the `show_stats` function in the `benchmark/benchmark.py` file. We will use the pandas and matplotlib libraries to create the bar plot.

Here are the steps:

1. In the `show_stats` function, after creating the DataFrame `df`, sort it based on "model" and "edit_format".
2. Group the DataFrame by "model" and "edit_format" and plot a bar graph for "pass_rate_1".

Here are the changes:

```python
benchmark/benchmark.py
<<<<<<< ORIGINAL
def show_stats(dirnames):
    rows = []
    for dirname in dirnames:
        row = summarize_results(dirname)
        rows.append(vars(row))

    df = pd.DataFrame.from_records(rows)
    df.sort_values(by=["model", "edit_format"], inplace=True)

    df_grouped = df.groupby("model")["pass_rate_1"].mean()
    df_grouped.plot(kind='barh', figsize=(10, 6))

    plt.xlabel('Pass Rate 1')
    plt.ylabel('Model')
    plt.title('Pass Rate 1 for each Model/Edit Format')
    plt.show()

    df.to_csv("tmp.benchmark.csv")

def show_stats(dirnames):
    rows = []
    for dirname in dirnames:
        row = summarize_results(dirname)
        rows.append(vars(row))

    df = pd.DataFrame.from_records(rows)
    df.sort_values(by=["model", "edit_format"], inplace=True)

    df_grouped = df.groupby(["model", "edit_format"])["pass_rate_1"].mean()
    df_grouped.unstack().plot(kind='barh', figsize=(10, 6))

    plt.xlabel('Pass Rate 1')
    plt.ylabel('Model')
    plt.title('Pass Rate 1 for each Model/Edit Format')
    plt.legend(title='Edit Format')
    plt.show()

    df.to_csv("tmp.benchmark.csv")
>>>>>>> UPDATED
```

This will create a bar graph with the average of "pass_rate_1" for each "edit_format" within each model. The bars for each model are grouped together.
