investigate using .editorconfig

[kilasuit]

.editorconfig is a well used way of sharing common configurations that are used across different editors & would help with onboarding new users to this repo. Optionally, or instead, in the Readme, perhaps add a bit of detail about any prefered editor the project is using

@kilasuit I think this project isn't that strict about coding styles, so at the moment I don't think we need a .editorconfig.
