📝 Remove Package.swift, add details to readme

[phatblat]

We've decided to not bother with updating the main branch to simplify deployment of our SwiftPM package release. This PR removes the Package.swift file from the repo and adds details to the readme for how users can find more info. After this change, the main branch is effectively just a README.md for humans and a link to the tags page where new versions will show up.

Also, the link to our iOS installation docs was broken as the URL has changed recently.

Perfect. 👌

Really sorry to resurrect an old PR with a new comment, but someone working with some new search functionality for the Swift Package Index came across the fact that the Package.swift file has been removed from this repo.

We rely really heavily on there being a Package.swift on the default branch to determine lots of the package metadata that we display on the package page. Removing one from a project that originally had one doesn't cause immediate problems, but we do remove packages that do this as they wouldn't pass validation if submitted in this state.

I'm writing a note here as it's going to break your SPI badges that you added to your README. We're thinking about ways to deal with this issue, but it's a situation that's quite tricky for us to cope with.

Hope it was OK to leave a note here!

Thanks for the reminder! This has been brought up a few times and we're planning to resurrect it, just need our deployment to update the main branch instead of creating orphaned branches (which was a little easier).

Ah, that's great news! Thanks for the very quick reply!

I've removed it from the index for now, but please do feel free to re-add it as soon as there's a Package.swift file again.
