+Migrate tests to C8/Chai/Mocha
+
+- `@testdeck` OOP testing has been removed.
+- Tests have been unified
+- CommonJS module mocking has been replaced through
+  refactoring of tests, as ES Modules cannot be mocked
+  (do yourself a favor and don't try to mock them)
+- C8 now replaces NYC as a native coverage tool
