Add padding to multiline modifier

[officebluesource]

Goals :soccer:

SkeletonUI uses GeometryReader to read the views size. GeometryReader is greedy and tacks all the size it gets. If I have a typical Layout like: HStack { Text("a") VStack { Text("a") Text("a") }.skeleton(true).multiline(...) }

This causes VStack to take the complete height of the container. Also the multiline is "blown" up. You can work around by applying extra constraints when the skeleton is there, but that increases the complexity of the layout a lout.

A simple solution is to add a padding option to the multiline modifier, this enables more flexibility when adding the skeleton.
