Swift package?

Would it be possible to make this a swift package?

After a brief attempt, I gave up trying to handle the varying ARC requirements between files. Swift Package Manager doesn't seem to allow specifying compiler flags per-file, only per-target. I looked around for any compiler pragmas that could turn ARC on/off within a file, but I came up empty. My next idea is to move the -fobjc-no-arc files into their own SPM target, then combine the targets into a single library product.

At that point, manual integration seemed easier, so I did that instead.

(Thank you for STULabel by the way! Link handling and truncationToken are very helpful.)
