Oops, I think I messed up while trying to make Flake8 styling modifications locally. I wanted to push my modifications on the remote historic_fires branch but the wrong local branch was pushed... I am looking for the simplest fix we could use.

EDIT: Just to keep this post up to date, after discussing the issue with Adel on Slack, we are going to make a new Pull Request and a new, clean remote branch tonight.

thanks for the PR guys, honestly not much to add, seems to work smoothly!

btw thanks for adopting the dead tree icon, I am well aware that it will be replaced at some point but it's nice to see it here :)

Shall we close this one ?

Yes, I just wanted to wait a bit before closing it, so that comments having disappeared from one PR to the other would not be surprising but we do not need it anymore.
