Robert Payne 40625f8ff9 Swift name annotations
Summary:
This adds `NS_SWIFT_NAME` annotations to all public API's to provide cleaner integration into Swift:

- Removes the need to prefix classes in Swift code, instead rely on Swift module name spacing
- Adds more argument labels to C function API's like `IGListDiff([], [], .equality)` => `ListDiff(oldArray: [], newArray: [], option: .equality)`

While this is a large API change it should be as easy as:

- Find and replace `(IGList)([^K])` to `List$2` in Xcode with a scope set to Swift
- Build and follow compiler's auto fix corrections for C API's or any missed renames

I have not updated the documentation to reflect this yet, I am totally willing to do so but before I sink that amount of time into it I wanted to see if the Instagram team is even open to this change!

- [x] All tests pass. Demo project builds and runs.
- [x] I added tests, an experiment, or detailed why my change isn't tested.
- [x] I added an entry to the `CHANGELOG.md` for any breaking changes, enhancements, or bug fixes.
- [x] I have reviewed the [contributing guide](https://github.com/Instagram/IGListKit/blob/master/.github/CONTRIBUTING.md)
- [ ] I have updated the documentation
Closes https://github.com/Instagram/IGListKit/pull/593
