Request - Storio2 build supporting AndroidX

[bomalone]

There is still some issue with Jetifier not properly handling the annotation processors. I have a large, legacy project that cannot easily go through a transition to Storio3, however, we desperately need to migrate to AndroidX. Is this something that someone familiar with this project can update? I have the source downloaded but do not have the time to find my way around, migrate it to AndroidX, and then make a PR.
