Documentation about onDetachedFromWindow

[ku8ar]

Regarding this:
DylanVann/react-native-fast-image#773
software-mansion/react-native-svg#1542
#773

From what I understand, for the libraries to work properly with react-native-screens, we need to change their lifecycle.
Recently, I found a new similar bug here: callstack/masked-view#114

And I could try to fix it, but I don't know how. Fixes in fast-image and svg have many commits and author himself wrote "that he is not sure that it work".

Therefore, I am asking for a nice and simple example of how component that supports react-native-screens should look like.

The double detach problem should be fixed in 3.4.0 and it was a bug on our side to call onDetachedFromWindow twice.
