[BUG] prms.whiten is modifying the components in PCA during transform() and inverse_transform()

[cjnolet]

I noticed this while investigating #2804. After training, nothing should be modifying the trained parameters, however, when whiten=True, the components are being modified in transform() and inverse_transform().

In this case, we should either be making a copy of the components, or possibly figure out how to perform the operations directly on the output.

@divyegala just wanted to ask since you're assigned if you have any updates on the status of this?

@dantegd sorry, no updates! Is it something we are trying to get in for 21.06?
