Use Material Motion library for transitions

This article describes lots of slick transition animations that would be fantastic to add to Presently.

Hey @alisonthemonster, are you open to migrating the project to Jetpack Compose, then build the animations afterwards?

I heard that animations are way easier in compose and it "might" be easier to take this path in the long term. (I think the project is also a good candidate as it satisfies the minSdk 21 requirement of compose)

@polbins Compose is definitely something I'd love to try in Presently! Do you think there's a good candidate for migration? Or do you have a strategy in mind for the migration?

I have yet to dig into compose so I don't know much about what would fit best with our current implementation. Maybe the entry view?

[polbins]

The migration code lab lists down 3 strategies:

1. Compose in new screens
2. Compose and Views together
3. Complete migration (migrate whole fragments or screens, one at a time)

I think it makes sense to go with the 3rd option for smaller screens, and go with the 2nd if ever the screen is too complex.

I'd be glad to try this on the entry fragment! Let me know if I can send a PR for it.
It's a big effort, but I think it would be worth it. :)
