Homebrew install error when using 0.12

Hi There,

When updating to 0.12 via Homebrew I get a missing library:

llm "hello"
Traceback (most recent call last):
  File "/opt/homebrew/bin/llm", line 5, in <module>
    from llm.cli import cli

    import six
ModuleNotFoundError: No module named 'six'

On Mac OS 13.3 M2 Pro

I'm not sure if this is to do with my python install but I've been a happy user on this environment up until now!

All the Best,
Alex

Start by reproducing llm "hello" with the Homebrew llm 0.12 installation on Python 3.12, then trace the import chain through llm.cli, llm/embeddings.py, sqlite_utils, and dateutil. Done means the command starts without ModuleNotFoundError: No module named 'six'.
