Subject: Get ava.py running with nixified builds

I had to redo some of my python overrides and crib the bitsandbytes.nix
from upstream.

Ava is failing because:

    ValueError: Tokenizer class LlamaTokenizer does not exist or is not
    currently imported.

I think this means I need to update my nixpkgs pin, so I'm gonna
snapshot my work in git, do the update, and that might obviate the local
bitsandbytes.nix anyway.
