Fix so SquidLib can be built without GPG junk
Fix so SquidLib can be built without GPG junk

I don't think anyone else can even do a release build to Maven Central
without my credentials, so it shouldn't require GPG signing for other
building people. JitPack already skips GPG signing steps with an
argument like `-Dgpg.skip`, so this shouldn't affect people using the
lib in that way, but it should make tests easier to run.
