Looks good! I like the default behavior being a warning versus automatic scaling.

In some instances of using PCovC, the latent space will "converge" very quickly with changing alpha. This happens because Z is not necessarily O(1) when computed within the
fitcall. This PR solves this by adding an argument to have a StandardFlexibleScaler call withinfitthat scales Z and W.This will break backwards compatibility but can be made backwards compatible by usingscale_z=False.Contributor (creator of PR) checklist
