Random access decryption in python?

[Keith Simmons]

I noticed that under the definition of keys for streaming AED, the docs mention random access is possible.  Also, from skimming the c++ source, I think there's a random access implementation here.  However, I couldn't find a corresponding equivalent in the python lib for tink.  Am I missing something?  Any plans to add this in the future?

Thanks for the great library!
