add support for Swift Package Manager

[jpsim]

Pointing to jpsim/Result for now because there's no tag of antitypical/Result containing Package.swift.

Due to swiftlang/swift-package-manager#16, I had to rename CommandantTests to Tests.

Could you open a pull request on antitypical/Result to add Package.swift? I'd prefer to have support there before we add support here.

[jpsim]

antitypical/Result already has a Package.swift but doesn't have a tag with it, which SPM needs. We could point this there, but it wouldn't work until a new release is made.

I just created a new release for antitypical/Result that includes the Package.swift. If you update this PR, we can merge it. It'd also be nice if we could test the linux build on CI, but I'm not sure what the state of that is.

[jpsim]

This is pointing to antitypical/Result now. Although Commandant Linux support is blocked on antitypical/Result#135, so I haven't included anything Linux-specific in this PR.

[jpsim]

I'll be tracking the Linux-specific Commandant changes here: jpsim/Commandant@spm...linux

Looks great! Thanks! ✨

It'd be great to cut a new release of Commandant with this change, so we can stop pointing other SPM projects to unofficial forks 😄 .

[mdiep]

I'll try to do that tonight or in the morning. 👍

[jpsim]

Thanks ✨

I just released 0.8.3. ✨

Fantastic, thanks!
