support .editorconfig

[matu3ba]

see https://editorconfig.org/:

Only forward slashes (/, not backslashes) are used as path separators and octothorpes (#) or semicolons (;) 
are used for comments. Comments should go on their own lines.

Comments are prefixed with #

For the neovim helpage: :h editorconfig.

I am not familiar with the in-documentation language highlighting or if you use it at all, but this would make things faster (probably also adding it into the README):

Huh? What's the point here? I thought you wanted to add to add support for editorconfig files(?)

Point being is that getting treesitter used filetype is not documented in :h filetype.

There's also :h comment.ft.calculate to get filetype/lang using treesitter.
