rdrand lacks .__version__ string

[garfi303]

Hi. Most python modules that we use implement a version string. For example, randomgen does:

Python 3.7.6 (default, Jan  8 2020, 19:59:22)
[GCC 7.3.0] :: Anaconda, Inc. on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import randomgen
>>> randomgen.__version__
'1.18.1'

But rdrand does not:

>>> import rdrand
>>> rdrand.__version__
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: module 'rdrand' has no attribute '__version__'
>>>
