That would also be a welcome addition.  It's been requested on
bugs.python.org at least a couple of times[1][2], and the C code
to do the conversions already exists (_PyLong_{As,From}_ByteArray
in longobject.c), so it wouldn't be too much work to implement.

The main problem would be deciding exactly what the API should be
and where to put it.
