Provide callbacks

[ggbetz]

Callback for langchain (for example):

from langchain.llms import OpenAI
from langchain.prompts import PromptTemplate
from langchain.chains import LLMChain

import logikon

# Configure logikon debugger
config = logikon.DebugConfig(report_to=your_mlops_platforms)
lgk_handler = logikon.CallbackHandler(config=config)

# Set up chain and register debugger
llm = OpenAI()
prompt = PromptTemplate(
    input_variables=["question"],
    template="{question} Reason carefully before submitting your choice.",
)
chain = LLMChain(llm=llm, prompt=prompt, callbacks=[lgk_handler])

# Run chain
print(chain.run("Vim or Emacs?", callbacks=[lgk_handler]))
