Support for Xcode 13

This pod can no longer be included in project in Xcode 13 as it needs to be compiled using Swift 5.5
Would be awesome to recompile it to stay up to date with latest tooling.

With this version, it works without any Swift version issue on xCode 13 : https://github.com/flockoffiles/SwiftySRP/blob/v3.0/

Hm, can't find this Url. The latest version here on the server looks to be using Swift 5, which gives me the above mentioned problem when adding pod into project.

I will try to spend some time and create a new release.

I pushed an update (3.1), but had to disable M1 Simulator support (to make it build with Carthage and Cocoapods) in the build settings.
