Subject: [PATCH] fix: include tests/__init__.py in sdist (resolves #341)

MANIFEST.in only listed README.rst and LICENSE. Because setup.py
excludes 'tests' from packages, setuptools dropped the package marker
tests/__init__.py from the source distribution while still shipping the
loose tests/test_*.py modules. A downstream build that does
'from tests import OrderedDict' (test_compliance.py) then fails with
ImportError: cannot import name 'OrderedDict' from 'tests'.

Adding 'recursive-include tests *.py' makes the sdist carry the
__init__.py package marker alongside the test modules.
