7.4.3

This release is all about minor optimizations, seems like there is a lot of that these days.
The layout algorithm for SpotsScrollView has been improved by moving the appropriate methods out of layoutViews.

When setting frames to views, the width is now floored before it gets set. This avoids using values with percentage in them.

The property sizeCache is now properly populated on iOS, this was only done on tvOS before.
