Currently, when a screen is replaced the new screen comes into focus with a push animation. However, sometimes you might want to customize how the animation looks like.
For example, when the user logs out, animating out the previous screen like pop feels more natural than doing a push animation with the sign in screen. The PR adds a new `animationTypeForReplace` option to control this. Specifying `animationTypeForReplace: 'pop'` will pop the previous screen, otherwise the new screen will be pushed like before.
