Code Review
This pull request adds a comprehensive set of tests for the raw and tar codecs, covering encoding, decoding, roundtrips, and error handling. The tests are well-written and use temporary directories effectively. My main feedback is to suggest adding t.Parallel() to each test function to allow them to run in parallel, which can speed up the test suite. This is a common Go testing practice for tests that do not have side effects on each other.
