Use tasty + tasty-golden for parse-examples tests.

These diffs are a prime example of golden testing: we want to match diff output exactly. If we use tasty as our prime test runner, we can use tasty-golden to set up a more accurate test of meaning (rather than just using shouldBe on a big string), and we’ll get pretty diff output without having to keep hspec-expectations-pretty-diff around (#116).
