Add .editorconfig support

[H3mul]

Currently, the formatter can only receive config via cli flags. In the absence of explicit configuration, it would make a lot of sense for the formatter to respect existing .editorconfig files, which is more or less standard across editors. This would reduce formatter setup between editors

Eg:

.editorconfig

root = true

[*]
charset = utf-8
indent_style = space
indent_size = 2

should be equivalent to gdscript-formatter --use-spaces --indent-size 2

Thanks for an awesome formatter!

u mean something like a toml configuration so one can avoid passing cli flags ?

Exactly - but also editorconfig is already widely used for consistent editor formatting:

https://editorconfig.org/

Plenty of projects already have a .editorconfig file like the one I quoted in their project root. My proposal is for gdscript-formatter to respect it if it exists (specifically regarding indentation)
