I think, but am still in the middle of testing, that with this series
applied first, I don't even need to worry about creating/applying a
PySlice object to a PyMemoryView.  Instead, I can copy a Py_buffer,
tweak the underlying pointer and length to match the subset in use,
the use PyMemoryView_FromBuffer.  The trickiest part will be getting
the reference counting correct.
