Add ElmLS (#9)

- Initial add of elmLS support
- Removes unnecessary vim.schedule_wrap fn calls in elmls & clangd impls
- Add automatic installation for elmls and update docs.
- Sort server output in the README.
- Add commands for elmls for buffer and globally.
- [bugfix] Skeleton could've tried to attach even if root_dir was nil

TODO: check for updates and warn the user if there are updates when an elm server is started.
