allow user-defined environment variable OPENAI_API_BASE_URL

[mike2194]

OpenAI API does not necessarily have to point to https://api.openai.com/v1/. user may wish to use something like http://ollama.local:11434/v1/

user-defined environment variable OPENAI_API_BASE_URL should override hard-coded base api url

That would be wonderfull. I also want to use it with my local llm setup (ollama) whicht has an openai compatible endpoint

This is already possible by adding

client.api_base = "http://your_llama.cpp.local/v1"

after client initialization, took me a minute to figure that out as well (actually had the environment var thing implemented and then thought wait ... ;) I made #15 to document this (and make luacheck happy).

For reference this would be how to do it with an environment var, i personally like it better modifying the client table in my script though to be honest
