Remove deprecated code

[Sachin-Bhat]

Hello @eyurtsev,

Here are the list of changes:

• kork/chain.py:
  • Removal of LLMChain in favor of RunnableSequence as per LCEL
  • Fixing some imports
  • Removal of pydantic.config.Extra and instead assigning literals to the extra attribute
  • Removal of cast() and predict_and_parse() in favor of .content and invoke()
• kork/parser.py:
  • convert the GRAMMAR to a raw string
• kork/prompt_adapter.py:
  • Fixing some imports
  • Removal of pydantic.config.Extra and instead assigning literals to the extra attribute
• tests/test_chain.py:
  • removing Chain.__call__() in favor of .invoke()
• tests/test_prompt_adapter.py:
  • Fixing some imports
• tests/utils.py:
  • Removal of pydantic.config.Extra and instead assigning literals to the extra attribute
  • addition of property _llm_type() to ensure that the test_chain passes since .invoke() needs this property to function correctly

Merging this fixes #24. Please let me know if further changes are required or if I have missed something.

Cheers,
Sachin

@eyurtsev are we planning a merge soon?

Hi @Sachin-Bhat,

Kork is a prototype for agents that can take multiple sequential actions at once, but it isn't really used by the community https://pypistats.org/packages/kork, so we're not maintaining it.

We can keep the PR open in case anything changes but for now it's hard to justify putting any work at all into this package.
