Remove bytestrings and use textwrap.dedent for readability

PyYAML works with and without bytestrings on PY3, and Python 3 can read
all of the test data as regular strings, so bytestrings are unnecessary
here.

This also adds use of textwrap.dedent to make the YAML easier to read,
so it can be indented away from the far left side of the line.
