Principled Texture Setup-Warning about unknown maps

Hi, I recently did an addition ( D14134 ) to Node Wrangler's Principled Texture Setup. The patch is waiting to be merged yet.

For those who don't know it, this is the most convenient way to load entire texture sets at once in the Shading Editor and connect them to the principled shader. This works based on the naming of the textures.

The problem is that there are many naming conventions and, while it works if you modify the name tags in the addon settings, maps with other identifiers will be ignored without any hint.

The simple solution would be a warning in the status bar that some maps you selected are not identified and you need to check the name tags. "x unknown maps; check tags in settings"
