Swift package support

Hi there! 👋

Thanks so much for the great work on this project! It solved a big issue I was facing getting metadata for some links. One thing I'd like to see is Swift package support, so I wanted to see if that is a possibility.

I'd also e more than happy to contribute this on a PR as well 😄

Thanks!

Hey,

I've attempted to add SPM support in the past however I kept running into issues trying to integrate Kanna because it needs LibXML2. So if you want to give it a go, go for it!

Thanks so much for the follow up! I can try taking a stab at it, so 🤞 .
