Update to use CryptoSwift 0.7.1

[eeu479]

The current build of JSONWebToken is using crypto swift 0.6.9.

I noticed the CI Build failed with commit "UPDATED to use crypto swift 0.7"

Has any progress been made on updating to use >0.7?

I have opened a pull request (#96) which brings the CryptoSwift version to 0.8.0 and fixes another issue which prevented successful builds. I have verified that builds are successful on both macOS and Linux. (The failing CI builds seem to be related to the unit tests rather than build errors.)

If you need to, you can use my fork at the master branch while the PR awaits review. I don’t plan on making any further changes that would break the project, so referencing the master branch should be harmless. Just remember to monitor #96 and revert back to this repo, assuming it’s approved, for future updates.

In case you don’t know how to reference a Swift package at its master branch (requires Swift 4):
.package(url: "https://github.com/jonblatho/JSONWebToken.swift.git", .branch("master"))
