Clean up noqa E241
Since we use black some of the whitespace codes for flake8 might not be applicable anymore. E241 in particular, which is for multiple spaces after a comma I don't think should appear anymore

A quick grep shows the following - if anyone would like to clean these up by deleting the noqa should make for an easy contributing I think

```sh
$ grep "# noqa: E241" -r pandas --include="*.py"
