fix: reset_index is not an argument

[CFisicaro]

apply_control function in this example, I realised that dataframe_intersection in pyhdx.support doesn't have reset_index as argument.

Thanks! I've made changes recently and frequently struggle to keep the examples up-to-date. It's good to hear its being used, so I'll try to be more strict in keeping those working.

Are you on the current master? The docs example runs for me, and the reset_index argument was added here recently by #318

I was using the old one, my bad! I pulled the new and indeed, it works now. Thank you!
