Xilem example for http cats API, requiring `worker`s and `image` component (#571)
This example is inspired by: https://troz.net/post/2024/swiftui-mac-2024/ Current status: - Lists status code - Can select status code - Downloads image from status code - Shows image from status code This adds two new features to Xilem: - The worker view, which is the obvious extension to `task` for multiple operations - The `image` view, which just uses Masonry `Image`. It also fixes a the Masonry Image view's layout to use the already extant but unused method.
