Feature request: add tailwindcss config path to the settings

[kareljan]

Is it possible to add the config path to the settings in VS code?
I sometimes work on websites with more than one layout. So I have different tailwind.config.js files in my project. It would be nice if I can change the config file the intellisense uses if I work on a different part of the site.

So a setting like "tailwindCSS.config" that I can set to "tailwind.config.projectA.js" or "tailwind.config.projectB.js" would be nice. And if the setting is not set, that it defaults to tailwind.config.js or tailwind.js
