Siren Versions Save

I simplified the code in Bundle+Extension.swift around the change made in Swift 5.7.0.

#357, #358: The resource bundle now properly loads when installing Siren via Swift Package Manger (minimum v5.3).

#355: Thanks to @hkellaway for adding a couple more countries that were missing from his #352 PR which added support for type safe App Store declarations. Specifically, Korea and The Maldives were added.

This is a version bump that only affects folks using SPM. This change results in less metadata files being brought into an installation now that the architecture of this repo has changed.

I took the time to cleanup the repository a bit prior to this release.

Notable changes (not related to the repo cleanup):

• #352: Thanks to @hkellaway's work, these is now explicit, type-safe support for every country that Apple has an App Store in. Checkout AppStoreCountry.swift
• Updated the minimum version to iOS 11
• Removed support for Carthage

• #348: Fixes iOS 14 presentation issue

• #351: Removed old UI code that may not have been working properly (thanks to @giofid for bringing this to my attention)
• Updated base support from 9.0 to 10.0

Thanks to @iKefir for his solution in #342 that fixes an issue with the after-effects of the Siren AlertController interfering with system AlertControllers.

Addresses: #335, #338, #341, #342.

Updated Package.swift and Podspec files to resolve https://github.com/SwiftPackageIndex/SwiftPackageIndex-Server/issues/399.

App installs again via all dependency managers.
