Feature request: respect editorconfig settings

[heapifyman]

Would be nice if marksman could take into account all editorconfig settings, like max_line_length, trim_trailing_whitespace, etc.

Supporting editorconfig indentation settings was already mentioned in #94. But I think it might be useful to also respect the rest of the "universal" settings.

For example, I have max_line_length = off for .md files but I still get warnings about MD013/line-length in neovim.
