Hubble should support multiple viewStates

[RaymondDashWu]

Summary & Description of Feature

Currently Hubble only has support for one viewState at a time in contrast to Deck, which can support multiple views and viewStates. If the user wants to use 2+ views they'll need more control over the viewState prop. Currently overwritten by Hubble during the animation here

Possibly adapter.getProps could be refactored to behave differently when the views prop is an array of two or more things, and figure out how to ensure this._getViewState() is nested under the correct key
