Add editorconfig

Do you feel that this adds much over the existing autoformatting (via pre-commit + ruff)? It feels more natural to me to have just a single place that handle this.

[patrick-kidger]

I'd cut these two. Right now we rarely use either kind of file and both are unformatted.

[NeilGirdhar]

This is for editors, not formatters. The indent size tells the editor how many spaces to add when "tab" is pressed. I got rid of the line length then.

[NeilGirdhar]

editorconfig automatically configures editors like vim, emacs, etc. so that they know how to save files, how long the lines should be (for examples, vim's automatic line width formatter), where to show the line length helper.

The problem is that I have my editor configured differently than yours. With this file, my editor automatically adjusts to your configuration.

[patrick-kidger]

Indeed, I'm familiar with .editorconfig.

My point is that if we care about such things then IMO it'd be better to have a single source of truth on such matters -- an autoformatter -- and allow anything at all whilst editing.

Anyway, not a strong opinion. *.py files are the only ones we attempt to format so trim this down to just that and I'd be happy to merge this.

Yes, I see your point. I guess I forgot that you've got the auto-formatter enabled.

Anyway, updated as requested.

Alright, merged! :) Thank you for the contribution!

[NeilGirdhar]

Thanks for being flexible about this :). Maybe we should propose to Ruff that editorconfig be the defaults to satisfy your "one source of truth" desire?

Seems not planned: astral-sh/ruff#1530

Ah, nice find!
