Compile time issue

[gpolyansky]

Hello! Look at the timeline of compilation of these files:
TransformPageView
TransformPageViewProtocol
TransformCurve

SPM
Xcode 14.1
Macbook Pro 16 m1 pro
macOS Monterrey

How we can reduce compile time?

I found some issues with optionals in TransformPageViewProtocol extension:

Please, could you refactor initialisation of PagePadding to make it not so hard with optional types.

To activate build time analytics just add -Xfrontend -warn-long-expression-type-checking=30 to project build settings at Other Swift Flags setting.

Hey Jerry,
Thanks for looking into this, we can definitely improve it.
Feel free to open a PR and improve the code.
I'll try to take a look and improve it as well.
