Replace SVG Skia with Resvg - rust

This can save 10 MB in binary size of FlyPhotos.exe

The Resvg works great for all the test svg files even though slow. Let Resvg run for two iterations (instead of SVG Skia) and see how many people raises bugs.

Seems to have a slight startup speed benefit too..
