[python-win32] Variant ByRef 2D array returned as 1D array

If the type of one dimension is VT_UI8, then pythoncom will treat that as a
'byte buffer', so will return a string - in which case you will simply need
to pretend the string is actually an array of bytes!  Otherwise you are
probably going to need to help create a test case so I can see exactly what
is going on - what language is this object implemented in, and is the source
available?  We have test COM objects written in VB and C, so creating a test
case shouldn't be too hard.
