v2.1.1 - Sendability

Make the LUUID type conform to Sendable.

Full Changelog: v2.1.0...v2.1.1

2.1.0 - SwiftPM Support

This adds support for Swift Package Manager.

Note: I do not have manager status for the original LUUID, so I am unable to update the cocoapod.
However, considering the change here is just adding SPM support, there's not much point making that available in cocoapods.
