Introduce mocking framework and increase coverage

BradleyBoutcher commented 3 years ago

This change introduces three common Golang patterns to the SonyFlake project test framework:

types: this will allow fine-tuned control over imported types by defining how they will be used, project-wide
mock: this allows the generation of mock constructors, which lends itself to testing any individual path in a function by "injecting" a mock object which matches the expected type
array-based-testing: privateIPv4 and lower16BitPrivateIP were lacking tests for their error paths, but using types and mocks, I was able add two array-based tests that cover all test cases for these methods

This change also increases test coverage to 💯, while adding no additional time for testing ⌛ .

This is a really cool project, and I'd be happy to contribute more!
