www/py-hyper: Update to 0.5.0

• Update PORTVERSION and distinfo checksum (0.5.0)
• Update RUN_DEPENDS
• Add TEST_DEPENDS and do-test: target. Note, we disable test_integration* tests because they hang, and I don't yet know why.
• Add test files that are not (yet [1]) included in the PyPI sdist

Changes: (No repository tag for v0.5.0 [2])
