Enable PyPy testing (#530)

* Skip failing tests on PyPy for now

* use move pypy3.9 into main tests

* never mind pypy is experimental then

* skip meticulous tests on pypy

* no cython w/pypy for now

* skip janky tests on pypy

* lint

* rename workflow

* add asyncio_mode = "auto" to pyproject.toml

* undo disabled tests in functional test_streams.py

* enable regular stream testing for unit tests
