feature suggestion: extract centroids described with original variables

[tomazweiss]

When a recipe contains step_pca() or some other feature extraction method, extract_centroids() will describe centroids with these new variables. Users may also be interested to see cluster descriptions with original input variables.

Hello @tomazweiss 👋

thank you for this feature request, it seems reasonable.

It feels like it would be an augment()-like operation. I need to think a little deeply to make sure it makes sense

After thinking about it for a while, I think this is going to be too hard to implement. It would be possible for some types of preprocessing to be able to go back to the original data. but some preprocessing methods are not reversible, so implementing this would be a half-job as some workflows would work and some would now. Sorry.
