Completes machine-aligned int2bytes implementation.

* This implementation is generally in microseconds
  instead of milliseconds, which makes it 20x-40x faster
  than the older implementation. Tests for all of the behavior
  of the function have been added to tests/test_transform.py.

 Hope this helps make python-rsa even better. =)
