I've got a csv file, where the first elements in each row contain sometimes an additional comma as part of the name. Since not all elements are put in quotation marks it will result in a messed up dataframe. I want to regard only the last n commas as commas, additional in the beginning should be deleted.

```
Example:
"name", "rank", "wealth"
Donald Trump, Jr, "45", "3"
Barack Obama, 44, 0

```

In this example, meaning dropping the first comma only in rows with more than 2 commas.
