Fix flake8 violations for all files in the asv/extern/ directory

[dorothykiz1]

We are trying to clean out all the files to follow Flake8 standards

Use this guide below to install flake8 and how to use it.
Flake8 guide

Here are a few steps to follow:

• You will be required to remove the files you would like to work on from the setup. cfg file under the extend attribute .
• Create a virtual environment virtualenv venv venv will be the name for the environment and activate it by running source venv/bin/activate these commands are dependent on the operating system. (These are Linux commands, you can find for windows and macOS online)
• Run pip install flake8 to install flake8
• Run flake8 --exclude="" asv/extern/ .
• Work on all the highlighted errors

Expected errors to be fixed:

Thanks @dorothykiz1 for creating those, very helpful, and the description is very clear.

I guess extern can mean that the code in the directory has been copied from elsewhere. Let's give low priority to this issue for now. Maybe it could make sense before fixing the style errors, to have a look and see where the code was copied from, and if things changed since it was copied (maybe there is a library now, or a newer version of the script...).

This can be closed now that extern has been removed as of #1234
