Convert Microsoft LDAP ObjectGuid from base64 to Python UUID

I needed to convert an objectGuid from Microsoft AD which was provided to me in base64. What I did not know is the Microsoft uses little-endian UUIDs instead of big-endian like the rest of world uses. This caused issues trying to convert the binary to UUID. Luckily, Python's UUID has bytes_le (little-endian) just for this use case.

Blogging this for the future.
