Prettier [sets](https://prettier.io/docs/en/options.html) `useTabs` to `false` and `tabWidth` to `2` by default, yet it is [changed](https://github.com/prettier/plugin-lua/blob/master/src/index.js#L59-L62) to `true` and `4` in this plugin. Is there any reason for this?
