3.1.0: Support Swift 5, use Apple bundled libxml2 🎉

[FEATURES]

• Switch to Swift 5.0.
• Use libxml2 that Apple bundles with the latest SDKs. This is a big enough ease of use change that I'm happy to require people build using Xcode 11.4, as it means no more weird module errors or libxml2 link failures.

3.0.6: Support more link types

[BUGFIXES]

• Don't require type attribute on <link> elements, and also don't require that a size exist in the type hints table, fall back to .classic type if it does not exist there. Closes #25. Thanks @winsmith!

3.0.5: Bugfixes, og:image support

[FEATURES]

• Modified behaviour of downloadPreferred(). Will download all available images, and then sort, once size is known, instead of relying only on pre-declared sizes, which are rarely available. This should give a higher quality result, however, this may result in slower performance for websites with large alternative images.
• Add support for og:image types (#24)

[BUGFIXES]

• Fix crash for malformed XML/HTML (#23)
• Update runtime search path for macOS target (#22)

3.0.4: Crash fixes.

• Fixes a crash if HTML or XML was empty (#20)

3.0.3: Bugfixes

• Fix build on Xcode 9.3
• Decrease deployment target versions

3.0.2: Bugfixes

• Allow icons to be defined inline in the HTML as well (Fixes #13)

3.0.1

• Turn off libxml2 warning/error output

3.0.0: Swift 4.0

Rewrite from the ground up in Swift 4.0, with same compatible public API.
Now available as a CocoaPod!

2.0.0: Swift 3 modern syntax

• [Breaking Change] API updated for modern Swift syntax by #10 (thanks @SolfaMode!)
  • Enum cases now start with lower-case character
  • Methods annotated with @escaping where the closure is being captured.
• Removed test dependency on DVR fork

1.0.9: Simplified deployment and usage

• Removed seperate LibXML2.framework, all of its classes have been rolled into FavIcon.framework, so only one framework to manage.
• Callbacks are now always invoked on the main queue, so you can set the result image on the UI immediately.
