feat(TopBottomPresentable): Adds 'TopBottomPresentable' protocol, allow any Animator to be presented correctly by the Presenter

[lifely]

The current implementation of Presenter check for a topBottomStyle using TopBottomAnimation.Style enum which allow during install to present the Message over or under navigation-bar and tab-bar.

However the current implementation of the topBottomStyle computed property limit all customisation of behaviour and only allow presentation in .top or .bottom style with the TopBottomAnimation animator.

I've implemented a simple TopBottomPresentable protocol which return the TopBottomAnimation.Style? behaviour needed; thus we can add conformance of this protocol to our existing TopBottomAnimation and PhysicsAnimation.

This would allow customisation in any Animator in the futur by simple conforming to TopBottomPresentable.

Hope this is convenient for other people as well and can make it in, I'll be available if you need any change or need to drop the last commit (podspecs & version change for my own use atm)

Seems like a good improvement. I’ll try to get to this soon, but I’m super busy right now
