FadeIn ContentView and TopBar when pushing shared element screen

If the screen is pushed with `animated: false` then only TopBar is
animated in. This is a compromise until we expose means to control the
transition of each element on the screen.

Reading the docs I couldn't see a way to simply change the color of the status bar on Android. Only via https://github.com/wix/react-native-navigation/issues/571#issuecomment-267255350 I saw there was a prop to do this.

(Assuming this is Android only since iOS only allows for light or dark).

* Temporarily disable shared element screens in example app

* Fix card positioning when transitioning

* resolve rnn dep from npm

* Temporarily disable shared element screens in example app

* Fix card positioning when transitioning

* Add view manager

* Don’t update screen style on ViewPagerScreenChangedEvent

* change version to legacy

* Fix headers after rebase

* version bump

* Add image to each list item

* Basics structure is done (I think)

toElement also animates into place, even though values are completely wrong.

* Stop relying on refs to resolve fromElements

* Hide only corresponding fromElement

* Animate sharedElements back into place on screen pop

* Update example project with Dota heroes

* Initial curved animation implementation

* Stop resolving sharedElement refs

* Move getLocationOnScreen to ViewUtils

* Parse control points passed from Js

* Scale animation works

Not sure about pivot coordinates yet.

* minor update to SharedElementsTransition screen

* Minor changes to example screens

* Draw shared elements on Screen

Ignore Z order and draw shared elements directly on screen

* stuff

* Start animation after views are drawn

* f

* Animate text color

* Less allocations when animating text color

* Switch from RGB to LAB 😎

* Save and restore SpannedString

* Use correct status bar height in Android M

* Pass show and hide duration from Js

* Fix flicker when show animation starts

* Make shared elements not clickable

motivation: might be related to some native crash

* Use linear interpolation as default interpolation

* Code cleanup

* Clear SharedElements refs when screen is destroyed

* Code cleanup

* Add decelerate interpolator

* No more occasional flicker on animation start (Hopefully 🙏)

* Add FastOutSlowIn interpolator

* Animate only visible shared elements

* Clip bounds animator somewhat works

* Hope fully no more flickery images

* Add interpolator to each animator

* some work on shared element screens

* rebase fix

* fix lint

* Global bottomTabSelected event

* ios - add bottomTabSelected and bottomTabDeselected events

_lede_ is a [word](https://www.merriam-webster.com/dictionary/lede), not a spelling mistake. In case you were wondering.

* Add font family support on bottom tabs

* import missing classes

* import missing class

* update document

* Added an additional navigation event for the press of an already selected tab

* Renamed new navigation event to bottomTabReselected

This is a quick hack to address issue where the expended color was
set after pop even if screen was collapsed.

No need to check it twice
