Add SwiftSoup as a package dependency
https://github.com/scinfu/SwiftSoup
SwiftSoup is a pure Swift library, cross-platform (macOS, iOS, tvOS, watchOS and Linux!), for working with real-world HTML. It provides a very convenient API for extracting and manipulating data, using the best of DOM, CSS, and jQuery-like methods. SwiftSoup implements the WHATWG HTML5 specification, and parses HTML to the same DOM as modern browsers do.
