Claude/Anthropic support was removed

[ADR-007]

First check

• I added a descriptive title to this issue.
• I used the GitHub search to try to find a similar issue and didn't find one.
• I searched the Marvin documentation for this issue.

Bug summary

The documentation and some old PRs say that Claude (Anthropic) LLM should be supported, but in reality, such functionality is not available.

I need to use both OpenAI and Claude on my project, and I would like to know if you have plans to support it. Thanks!

Reproduction

# follow the documentation:
# https://www.askmarvin.ai/utilities%20%28old%29/chat_completion/#basic-use

from marvin import ChatCompletion
import os

os.environ['ANTHROPIC_API_KEY'] = 'anthropic_private_key'

# Set up a dummy list of messages.
messages = [{'role': 'user', 'content': 'Hey! How are you?'}]

# Call claude-2 simply by specifying it inside of ChatCompletion.
anthropic = ChatCompletion('claude-2').create(messages = messages)

print(anthropic.choices[0].message.content)
# I'm doing well, thanks for asking!

Error

There is no "ChatCompletion" or anything that mentions Claude/Anthropic in the source code.

hi @ADR-007 - anthropic support was removed with the release of marvin 2.x and would need to be implemented according to new tool use paradigms in the anthropic APIs - we'd like to add support soon and would welcome / guide any contributions!
