Subject: [PATCH] fix hashlib usage compatibility with pypy3
PyPy3's hashlib fails when passed a memoryview object (i.e.
BytesIO.getbuffer()). Convert it to bytes instead in order to fix
compatibility. While this isn't necessary for CPython, it should not
cause any issues.
Also enabling testing with pypy3. I had to switch to the newer Ubuntu
version as well in order to avoid more bugs in old PyPy versions.
PyPy3 bug: https://foss.heptapod.net/pypy/pypy/issues/3217
