Add simonw/llm as cli/library client for running LLMs

This is basically exactly the client library that I would write myself. Some
parts of it are still beta quality, but it's the sort of thing that I would
contribute to anyway.

Unfortunately I couldn't get the llm-llama-cpp plugin to work because it depends
on llama-cpp-python which is not packaged for nix and is hard to package because
the upstream project vendors a patched version of llama.cpp. So I'm stuck with
ollama for now, but that's fine because it actually works.
